It delivers highl y precise gamma radiation from 192 high-activity cobalt-60 sources. Each s ector of the Leksell Gamma Knife Perfexion (PFX) contains 24 cobalt-60 sou rces and can move independently between five different positions. Three of these positions correspond to collimator sizes of 4\, 8\, and 16 mm\, whi le the other two are a blocked position and a home position. Leksell Gamma Plan version 11.0.3 (LGP\, Elekta Instruments)\, which is used to design t reatment plans for the Leksell Gamma Knife (LGK)\, calculates the patient' s absorbed dose using the Tissue Maximum Ratio (TMR) algorithm. However\, since the TMR algorithm assumes that all material within the patient is eq uivalent to water\, it introduces an inherent error due to the actual hete rogeneity of tissues.\nThe effects of this error have been evaluated in se veral studies using Monte Carlo (MC) simulations. Additionally\, MC simula tions have become increasingly common for assessing shaped and small-field radiation beams\, as they are the most reliable tool for determining dosi metric quantities. The effects of this error have been evaluated in severa l studies using Monte Carlo (MC) simulations. Additionally\, MC simulation s have become increasingly common for assessing shaped and small-field rad iation beams\, as they are the most reliable tool for determining dosimetr ic quantities. However\, these simulations require extensive computation t ime to determine absorbed doses\, particularly for small-field beams like those used in the Leksell Gamma Knife (LGK).\nIn order to reduce the time required for simulations a unique phase space method was proposed to simpl ify all repetitive steps in the process. First\, the three collimators of different sizes (4\, 8\, and 16 mm) are created with precise geometric acc uracy. Then\, the exact positions (θ\, ϕ) of the 24 sources in each sect or are calculated. Subsequently\, the unique phase space is then rotated a ccording to these coordinates\, and the 24 sources are combined to form th e first sector. The unique phase space is then rotated according to these coordinates\, and the 24 sources are combined to form the first sector. To account for all eight sectors in each simulation\, this sector is rotated in 45-degree increments around the Z-axis.\nFor each phase space file (PS F) corresponding to each collimator\, 1.0 × 10⁸ primary photons were ge nerated. The phase space data files contain detailed information about the particle type\, energy (E)\, statistical weight (w)\, Cartesian position components (x\, y\, z)\, and directional components of linear momentum (u\ , v\, w). Using these phase space data files for the LGK PFX\, a first-in\ , first-out (fifo) method was employed\, which first reads a file with the angular positions (θ\, ϕ) of each sector\, followed by reading the PSF and applying the respective θ and ϕ rotations for each sector. This proc ess is repeated sequentially from sector 1 to sector 8. Thus\, a second ph ase space file (PSF2) can be created to contain the information for one se ctor\, all sectors\, or even interchanged sectors as required by the treat ment plan.\nFor the PSF2\, 1 × 10¹⁵ histories were defined\, using dif ferent initial seed values for the random number generator. The results of this simulation\, using the developed method\, were validated by comparin g the phase space interacting with a 160 mm diameter spherical phantom aga inst the results obtained from radiochromic film measurements at the Ruber International Hospital in Madrid\, Spain.\nDose profiles were calculated along the X\, Y\, and Z axes using the general configuration of PenEasy\, as well as 2D dose maps\, which were compared with dose distributions meas ured with radiochromic film. A good agreement was achieved for the dose pr ofiles\, especially in the central region with a maximum discrepancy of le ss than 2%. Conversely\, the largest difference\, of less than 5%\, was no ted in the penumbra region. This demonstrated excellent concordance for al l three collimators.\n\nhttps://indico.ific.uv.es/event/7664/contributions /25510/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25510/ END:VEVENT BEGIN:VEVENT SUMMARY:LUNCH DTSTART;VALUE=DATE-TIME:20241121T122500Z DTEND;VALUE=DATE-TIME:20241121T135500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-24579@indico.ific.uv.es DESCRIPTION:https://indico.ific.uv.es/event/7664/contributions/24579/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/24579/ END:VEVENT BEGIN:VEVENT SUMMARY:European Strategy for Particle Physics.

Each pl ane features one LaBr3 crystal of size 25.8 mm x 25.8 mm x 5 mm\, coupled to a SiPM array. The system was initially tested with phantoms filled with FDG and I-131\, as well as thyroid cancer patients in collaboration with La Fe Hospital (Valencia). Following these tests\, studies with alpha emit ters were also conducted. In addition to Monte Carlo detailed simulations that indicated the potential for imaging Ac-225\, this isotope was also su ccessfully imaged experimentally in collaboration with the Léon Bérard h ospital in Lyon.\n\nHowever\, these measurements evinced the lack of effic iency of MACACO III which has prompted the use of larger detector planes. MACACO III+ is a two-plane system in which the first plane is the same as in MACACO III and the second plane is composed of four such detectors. Sim ulations show the benefits of this improvement in the reconstructed images . MACACO III+ has been tested experimentally with Derenzo-like phantoms an d also with mouse phantoms and live mice. Further tests are foreseen and a nother four-detector plane is under development.\n\nhttps://indico.ific.uv .es/event/7664/contributions/25505/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25505/ END:VEVENT BEGIN:VEVENT SUMMARY:Correction of Relative Efficiency in Radiochromic Films for Low-En ergy Proton Beams: An Experimental and Monte Carlo Study DTSTART;VALUE=DATE-TIME:20241119T144600Z DTEND;VALUE=DATE-TIME:20241119T145600Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25516@indico.ific.uv.es DESCRIPTION:Speakers: Adrián Zazpe (Universidad Complutense de Madrid)\nR adiochromic films (RCFs) have been widely used for dosimetry in photon\, e lectron\, and proton radiation therapy due to their tissue-equivalent resp onse and high spatial resolution. However\, when used with proton beams\, especially at energies below 20 MeV\, RCFs exhibit dose underestimation\, a phenomenon known as LET quenching. This underestimation necessitates the application of a Relative Efficiency (RE) correction factor\, which accou nts for the reduced dose response of the film as the Linear Energy Transfe r (LET) increases.\nIn this study\, we propose an optimized model for corr ecting the RE of EBT3 radiochromic films irradiated with low-energy proton s. Previous models\, such as the Sánchez-Parcerisa 2021 model\, have atte mpted to describe RE as a linear function of LET\, with limited success in high-LET regions. To address this\, we conducted a series of irradiations at the Centro de Microanálisis de Materiales (CMAM) using proton beams w ith an energy of 10 MeV and measured dose distributions in stacks of unlam inated EBT3 films. Additionally\, materials such as PDMS\, Flexdym™\, an d glass were placed in the beam path to evaluate the effects on the dose a nd LET distributions. The experimental dose values were compared to Monte Carlo simulations conducted using the TOPAS toolkit\, where scoring for do se and LET in the active layer of the films was performed.\nOur results de monstrate a significant discrepancy between the measured and simulated dos es in regions with high LET. The current Sánchez-Parcerisa model was unab le to fully account for this loss in RE\, particularly for LET values abov e 20 KeV/um. Through the application of a bootstrapping technique\, we dev eloped a new model to fit experimental data to an improved RE(LET) functio n. This model\, validated through uncertainty analysis\, shows a substanti al improvement in predicting dose in high-LET regions compared to the prev ious model.\nPreliminary findings suggest that the optimized model provide s more accurate dose predictions for proton energies below 10 MeV\, reduci ng the uncertainties observed in the experimental data. This correction wi ll enable a more precise dose estimation in proton therapy\, especially in applications where low-energy protons are used\, improving treatment outc omes.\n\nhttps://indico.ific.uv.es/event/7664/contributions/25516/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25516/ END:VEVENT BEGIN:VEVENT SUMMARY:Discussion on European strategy - with instrumentation and LHC DTSTART;VALUE=DATE-TIME:20241120T100000Z DTEND;VALUE=DATE-TIME:20241120T103000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25610@indico.ific.uv.es DESCRIPTION:https://indico.ific.uv.es/event/7664/contributions/25610/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25610/ END:VEVENT BEGIN:VEVENT SUMMARY:Discussion on DRDs - with instrumentation network DTSTART;VALUE=DATE-TIME:20241120T091500Z DTEND;VALUE=DATE-TIME:20241120T100000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25609@indico.ific.uv.es DESCRIPTION:https://indico.ific.uv.es/event/7664/contributions/25609/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25609/ END:VEVENT BEGIN:VEVENT SUMMARY:New physics from two-particle correlations DTSTART;VALUE=DATE-TIME:20241119T155500Z DTEND;VALUE=DATE-TIME:20241119T160500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25608@indico.ific.uv.es DESCRIPTION:Speakers: Emanuela Musumeci (IFIC)\, Emanuela Musumeci (Instit uto de Física Corpuscular (IFIC))\nhttps://indico.ific.uv.es/event/7664/c ontributions/25608/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25608/ END:VEVENT BEGIN:VEVENT SUMMARY:Inputs for future colliders from Spanish and European Early Career Researchers DTSTART;VALUE=DATE-TIME:20241119T132000Z DTEND;VALUE=DATE-TIME:20241119T133500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25607@indico.ific.uv.es DESCRIPTION:Speakers: Cristina Martín Pérez (CIEMAT)\nhttps://indico.ifi c.uv.es/event/7664/contributions/25607/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25607/ END:VEVENT BEGIN:VEVENT SUMMARY:Spanish ECR survey results DTSTART;VALUE=DATE-TIME:20241119T114000Z DTEND;VALUE=DATE-TIME:20241119T120000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25363@indico.ific.uv.es DESCRIPTION:Speakers: Lourdes Urda (CIEMAT)\nhttps://indico.ific.uv.es/eve nt/7664/contributions/25363/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25363/ END:VEVENT BEGIN:VEVENT SUMMARY:ECFA ECR input for ESSPU + WGs (European view) DTSTART;VALUE=DATE-TIME:20241119T112500Z DTEND;VALUE=DATE-TIME:20241119T114000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25606@indico.ific.uv.es DESCRIPTION:Speakers: Emanuela Musumeci (IFIC)\nhttps://indico.ific.uv.es/ event/7664/contributions/25606/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25606/ END:VEVENT BEGIN:VEVENT SUMMARY:ESPPU Discussion DTSTART;VALUE=DATE-TIME:20241120T100000Z DTEND;VALUE=DATE-TIME:20241120T103000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25585@indico.ific.uv.es DESCRIPTION:Joint session with LHC network and Future Accelerators network .\n\nhttps://indico.ific.uv.es/event/7664/contributions/25585/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25585/ END:VEVENT BEGIN:VEVENT SUMMARY:Detector R&D colllaborations discussion DTSTART;VALUE=DATE-TIME:20241120T091500Z DTEND;VALUE=DATE-TIME:20241120T100000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25584@indico.ific.uv.es DESCRIPTION:Speakers: MaryCruz Fouz (CIEMAT)\nJoint session with Future Ac celerators Network\n\nhttps://indico.ific.uv.es/event/7664/contributions/2 5584/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25584/ END:VEVENT BEGIN:VEVENT SUMMARY:News and Instrumentation School discussion DTSTART;VALUE=DATE-TIME:20241120T080000Z DTEND;VALUE=DATE-TIME:20241120T091500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25583@indico.ific.uv.es DESCRIPTION:Speakers: Ivan Vila Alvarez (Instituto de Física de Cantabria (CSIC-UC))\nhttps://indico.ific.uv.es/event/7664/contributions/25583/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25583/ END:VEVENT BEGIN:VEVENT SUMMARY:The SBND X-ARAPUCA system DTSTART;VALUE=DATE-TIME:20241119T153000Z DTEND;VALUE=DATE-TIME:20241119T154200Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25527@indico.ific.uv.es DESCRIPTION:Speakers: Jorge Romeo (CIEMAT)\nSBND is a time-projection cham ber that collects ionisation electrons and scintillation photons from liqu id argon (LArTPC). It is located 110 m downstream the Booster Neutrino Bea m target at Fermilab and began taking data this year. The SBND physics pro gram is focused on neutrino-argon cross-sections and beyond the Standard M odel searches (sterile neutrinos\, heavy neutral leptons\, light dark matt er...). The photodetection system (PDS) provides trigger capabilities\, co smic-rays rejection (a large background due to the near-surface detector l ocation)\, and complementary calorimetry. The PDS includes PMTs and X-ARAP UCAs sensors\, a novel technology that features single photo-electron reso lution at cryogenic temperatures with large area coverage in a cost-effect ive fashion by trapping and guiding the light to arrays of SiPMs. SBND fea tures two types of X-ARAPUCAs\, one mostly sensitive to vacuum ultra-viole t (VUV) scintillation and one sensitive to visible light produced in the d etector by TPB-coated reflective foils. SBND is the only experiment curren tly testing the X-ARAPUCA technology in a neutrino beam over a period of s everal years\, and will provide key lessons for future detectors like DUNE . In order to characterize the sensor it is essential to estimate its phot on detection efficiency (PDE).

Characterizing these se condary neutrons has implications across multiple fields\, including envir onmental radioactivity [1]\, single event upsets (SEUs) in microelectronic s [2]\, cosmic-ray physics\, and space weather [3].\n\nThe High Efficiency Neutron Spectrometry Array (HENSA) project focuses on designing\, develop ing\, and utilizing high-efficiency neutron spectrometers [4]. The latest iteration\, HENSA++\, has been specifically optimized for studying cosmic- ray neutrons and their applications in space weather monitoring and enviro nmental dosimetry. HENSA++ operates on the same principles as Bonner Spher e Spectrometers (BSS) [5]\, but with topological modifications in detector geometry\, achieving up to a tenfold increase in detection efficiency com pared to standard BSS [6]. The HENSA++ array comprises sixteen He-3 tubes\ , each one surrounded by different materials\, including high-density poly ethylene moderators\, cadmium shielding\, and lead neutron multipliers\, p roviding spectral sensitivity across a range from thermal to GeV neutrons. \n\nIn this work\, we discuss the current status and mid-term perspectives of HENSA++. Preliminary results from the recent commissioning of the spec trometer and laboratory measurements conducted during solar storm conditio ns in 2024 will be presented. We will also outline future plans to install HENSA++ as a permanent cosmic-ray neutron monitoring station at the high- altitude Observatorio Astrofísico de Javalambre (OAJ).\n\n\nBibliography: \n[1] European Radiation Dosimetry Group (2004).

Javier Galindo Guarch (Instituto Tecnológico d e Aragón)\nThe rapid evolution in high-luminosity colliders necessitates ultra-precise timing detectors capable of picosecond-level accuracy. This presentation explores the development of a distributed timing architecture based on deterministic protocols\, as the High Accuracy Default PTP Profi le of IEEE1588-2019 – a.k.a. White Rabbit (WR)\, to address stringent ti ming demands in next-generation particle detectors. Our primary objective is to implement a scalable timing distribution system that delivers a cloc king signal enabling an absolute time reference among different detectors. The system automatically copes perturbations influencing the distribution network\, as thermal cycles\, to overcome inherent instabilities and limi tations.

Many developments in instrumentation are related to photosensors\, microelectronics\, and space technology\, with key contributions to intern ational projects such as LHCb\, CTA\, HERD\, LISA\, ARIEL\, and axion dete ctors. Furthermore\, this technology is also being applied in medical imag ing and other fields in cooperation with academic and industrial partners. \nIn the particle detector field\, the Technological Unit has long partici pated in the LHCb project\, specifically in the Calorimeter sub-detector w ith PMT electronics readout. In recent years\, phase I of the upgrade was completed\, and the new low-noise analog ASIC has been producing data sinc e 2022. Additionally\, a new ASIC is being designed for phase II of the up grade for the High Luminosity LHC to meet the new stringent conditions of the detector.\nRegarding high-energy astrophysics\, ICCUB has developed th ree different chips with significant contributions to the CTA cameras. Mor e than 100\,000 chips have been produced to equip 15 cameras\, and there a re plans to consolidate this contribution with additional chip production and participation in the commissioning at the North site in La Palma. An u pgrade featuring new versions of chips with enhanced performance based on SiPM sensors is planned.\nThe unit is also involved in space missions\, su ch as the High Energy cosmic-Radiation Detection (HERD) experiment\, propo sed to search for signatures of the annihilation/decay products of dark ma tter\, among other key measurements. The Beta ASIC designed for the Fiber Tracker and PSD subdetectors is crucial to this effort. Additionally\, the Technological Unit is developing a radiation monitor for the LISA mission \, a constellation of three satellites in heliocentric orbit dedicated to gravitational wave observations by ESA.\nOther instrumentation contributio ns include radiopure electronics for the International Axion Observatory ( IAXO)\, a next-generation axion helioscope aimed at the search for solar a xions and axion-like particles (ALPs).\nLastly\, the medical imaging secti on of ICCUB makes use of the ASICS developed.

Recently\, with the advent of machine learning techniques in scie nce\, the method of Neural-Network Quantum States is being adopted by diff erent groups to tackle nuclear systems\, with the hope that it will be mor e efficient than the alternatives.

In this ta lk\, I present our latest optimizer\, Decisional Gradient Descent\, from t he point of view of second-order optimization theory.

Several and well-motivated NP scenario s suggest FIPs particles preferably coupled to muons as: Z' bosons in $L_{ \\mu}-L_{\\tau}$ models as one of the remaining explanation of the g-2 ano maly and the DM puzzle\; Dark Photons as a portal to DM with masses above 300 MeV which are neither accessible with electron or positron beams\; FIP s can also mediate Lepton Flavour Violation (LFV) processes such as μN → τX or μN → eX conversion processes and many more as scalar\, ALPs\ , millicharged particles\,… The goal of NA64μ is to search for FIPs usi ng the unique high energy and high intensity muon beam at CERN SPS. In thi s talk\, I will describe the first published results recently using $1.98\ \times10^{10}$ muons on target and the future prospects of the experiment. \n\nhttps://indico.ific.uv.es/event/7664/contributions/25413/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25413/ END:VEVENT BEGIN:VEVENT SUMMARY:The Underground Argon program of the Global Ar Dark Matter Collabo ration DTSTART;VALUE=DATE-TIME:20241119T155000Z DTEND;VALUE=DATE-TIME:20241119T160500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25414@indico.ific.uv.es DESCRIPTION:Speakers: Daniel Díaz Mairena (CIEMAT)\nDarkSide-20k is under construction at LNGS and is designed to lead the search for heavy WIMPs i n the coming years.

The detector consists of 3.3 tons o f Lar contained in a spherical acrylic vessel. At WIMP masses of 100 GeV\, DEAP-3600 has a projected sensitivity of 10−46 cm2 for the spin indepen dent elastic scattering cross section of WIMPs. External radioactive sourc es can be used to measure the energy calibration and to test the position reconstruction in the energy region of interest for WIMP signals. One of t he most effective sources is Na-22 which is deployed in a tube located aro und the DEAP steel shell. Na-22 decays to an excited state of Ne-22 via a β +-decay\, which de-excites by emitting a 1275 keV γ. The positron from the source decay annihilates resulting in the emission of two back-to-bac k 511 keV γ. The emission of the three γ particles following the Na-22 d ecay is nearly simultaneous\, providing a very effective tagging algorithm for Na-22 decays to distinguish them from backgrounds in DEAP-3600. In th is talk I will present the energy response and position reconstruction in DEAP-3600 with the Na-22 source.\n\nhttps://indico.ific.uv.es/event/7664/c ontributions/25415/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25415/ END:VEVENT BEGIN:VEVENT SUMMARY:IAXO: Simulations\, detector shielding and first results of the IA XO-D1 detector for the BAbyIAXO intermediate step at Zaragoza DTSTART;VALUE=DATE-TIME:20241119T163500Z DTEND;VALUE=DATE-TIME:20241119T165000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25542@indico.ific.uv.es DESCRIPTION:Speakers: Jorge Porrón Lafuente (Universidad de Zaragoza)\nht tps://indico.ific.uv.es/event/7664/contributions/25542/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25542/ END:VEVENT BEGIN:VEVENT SUMMARY:RENATA status DTSTART;VALUE=DATE-TIME:20241119T130000Z DTEND;VALUE=DATE-TIME:20241119T131500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25541@indico.ific.uv.es DESCRIPTION:Speakers: Maria Martinez (Universidad de Zaragoza)\nhttps://in dico.ific.uv.es/event/7664/contributions/25541/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25541/ END:VEVENT BEGIN:VEVENT SUMMARY:EFT analysis of the COHERENT experiment with RH neutrinos DTSTART;VALUE=DATE-TIME:20241119T144500Z DTEND;VALUE=DATE-TIME:20241119T150000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25397@indico.ific.uv.es DESCRIPTION:Speakers: Sergio de la Cruz Alzaga (IFIC\, CSIC-UV)\nUsing an effective field theory approach\, we study coherent neutrino scattering on nuclei\, in the setup pertinent to the COHERENT experiment.

IFIC’s TMS ha s been deployed on a large scale\, demonstrated by its operation at CERN\, monitoring temperatures along an 8-meter vertical column with 3 mK resolu tion in the DUNE prototype. This setup offers exceptional resolution with extensive sensor arrays\, making it ideal for large TPC instrumentation.

These differences are known as the “Reactor Antineutrino A nomaly” and the spectral “bump” [2]. The e-shape collaboration looks for solutions for these problems via the improvement of relevant nuclear models used in the calculation of antineutrino spectra from reactors [3]. The collaboration uses the summation method [4] to calculate predictions o f reactors’ antineutrino spectra due to its improved results over other methods\, and electron $\\Delta$E-E detectors to measure the beta spectra of relevant contributors to the antineutrino spectra [5]. Measurements of beta shapes were conducted at IGISOL-4 because the facility has a double P enning trap (JYFLTRAP) that produces isotopically clean radioactive beams of the isotopes of interest.

Although they offer numerous advantages\, such as high gain\, excellent temporal resolut ion\, and insensitivity to magnetic fields\, SiPMs also have some drawback s\, the most notable being correlated noise and device non-linearity. The study of these issues has been one of the research lines pursued by the Hi gh Energy Group (GAE) at UCM in recent years [1\,2\,3\,4]. This presentati on will discuss the results of GAE's work in understanding and addressing these problems.\nTo model non-linearity\, a mathematical expression is pro posed that relates the number of incident photons to the charge released b y SiPMs for light pulses of arbitrary shape and intensity. This expression introduces a simple model for the charge recovery of SiPM microcells afte r an initial avalanche\, which remains valid even after hundreds of avalan ches in the same microcell. This expression also takes into account variou s factors that affect the response of SiPMs\, such as the finite number of cells\, correlated noise\, and the shape of the incident light pulse. To study such a high level of saturation a detailed Monte Carlo simulation co de was developed. Both the code and the expression have been validated by comparison with experimental data. \nTo characterize correlated noise\, de tailed software tools are being developed for waveform analysis\, they are also useful for other typical measurements associated with SiPMs such as dark current rate and PDE. These tools can produce very clear finger plots as well as identify different kinds of correlated noise\nFinally\, the co llaborations that GAE has had with other research groups will also be disc ussed\, where these tools have begun to be used\, as well as future work i n this line of research.\n\n[1] L.

A smaller prototype\, BabyIAXO\, is c urrently in manufacturing and is expected to be installed at DESY (Hamburg \, Germany). A baseline detector prototype\, IAXO-D0\, is at present under going tests at the premises of the Universidad de Zaragoza. The prototype is sensitive to background that could induce false positive axion detectio ns\, and in particular to ambient neutrons of high energy. \nA neutron mon itor has been proposed as a way to provide a continuous measurement of amb ient neutrons and its variability. Neutron Monitors are typically used as cosmic ray detectors\, and consist of several neutron counter detectors su rrounded by a series of layers that act as reflector\, multiplier and mode rator for the neutrons. \nIn this work a prototype neutron monitor was des igned and assembled. It consists of three identical LND He-3 proportional counter tubes surrounded by a high density polyethylene (HDPE) moderator\, a layer of lead that acts as multiplier\, and an outer layer of HDPE as r eflector. The neutron monitor has been in operation since March 2024\, pro ducing an almost continuous measurement of the count rate of neutrons dete cted inside the laboratory where IAXO-D0 is being commissioned. \nWe will present the Monte Carlo simulations performed to characterise the monitor and the first results of the monitoring of the neutron count rate\, once n oise and pile-up have been taken care of\, and atmospheric pressure effect s have been corrected. \nThe information learned from this prototype neutr on monitor will guide the design of a neutron monitor optimised for neutro ns of around >100 MeV tailored to the IAXO-D0 needs.

Mo nitoring neutron dose rates is essential for assessing the risk to workers \, patients\, and the public\, particularly in particle therapy centers. S uch treatments\, often recommended for young and pediatric patients\, offe r the benefits of a reduced overall dose and high radiobiological effectiv eness. Proton beams are typically used\, though recent advancements are fo cusing on light ions such as carbon\, helium\, and oxygen. Since the prima ry beam energy ranges in the hundreds of MeV\, nuclear interactions betwee n high-energy particles and beam-shaping elements—or even the patient— result in the production of secondary neutrons. Additional factors influen cing neutron production include the accelerator technology\, room design a nd treatment plan.\n\nFor instance\, modern compact proton therapy units\, such as those based on superconducting synchrocyclotron technology\, prod uce pulsed neutron fields characterized by intense bursts of neutrons with in a short time frame. In this scenario\, many commercial dosimeters under estimate neutron ambient doses by up to a factor 10 [1]. A similar situati on is expected occur in innovative treatment approaches such as the Ultra- High Dose Rate Radiation (FLASH therapy) [2]. As accelerator technology ad vances\, so must the instrumentation used to measure radiation [3]. To add ress this gap\, we propose the LINrem project as a potential solution. LIN rem dosimeters are specifically designed to provide accurate neutron dose measurements under challenging conditions\, such as those found in particl e therapy facilities.\n\nThis contribution discusses the status and future directions of the LINrem project. We outline the design of a new passive LINrem dosimeter\, developed by replacing the active sensor in the LINrem moderator with thermoluminescent dosimeters (TLDs). We also present the va lidation of LINrem dosimeters in a high-energy reference neutron field\, w ith measurements conducted at CERN's CERF facility [4\,5]. This facility s imulates both\, cosmic-ray neutron spectra at altitudes of 10–20 km and the secondary spectra found in particle therapy environments. Furthermore\ , regarding clinical applications\, we provide preliminary results from an ongoing intercomparison campaign at the West German Proton Therapy Center (WPE) in Essen.

In PET\ , achieving a good coincidence resolving time (CRT) between detector pairs enhances the Time-of-Flight (TOF) information for each detected coinciden ce\, which significantly improves the signal-to-noise ratio of the images. This study introduces a method to train models\, based on the newly-devel oped Kolmogorov-Arnold networks (KANs)\, for assigning precise timestamps to incoming radiation signals in each detector. We trained the models with event pairs consisting of a measured event and its copy delayed a know am ount of time where the delay acted as a label during training. Trained mod els were evaluated using data from a 60Co point source and a pair of conic 2” LaBr3(Ce) detectors in coincidence mode\, connected to Hamamatsu R97 79 PMTs sampled at 5 Gs/s. We report that our method has achieved a 6% inc rease in CTR and around 40% increased accuracy in source location compared to the widely used constant fraction discrimintation (CFD) method for the evaluation set.\n\nhttps://indico.ific.uv.es/event/7664/contributions/255 07/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25507/ END:VEVENT BEGIN:VEVENT SUMMARY:New detectors for breast cancer Imaging DTSTART;VALUE=DATE-TIME:20241119T131500Z DTEND;VALUE=DATE-TIME:20241119T132700Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25508@indico.ific.uv.es DESCRIPTION:Speakers: Sara Gaitán Domínguez ()\nDevelopment of a new low -cost Molecular Imaging detector for breast cancer screening\, using silic on photomultipliers (SiPMs) and tiled Cesium Iodide (CsI) scintillators.

As f or neutron monitoring\, a drawback of most of the available systems is tha t only integral off-field neutron-fluence values are registered but no inf ormation is obtained from its spatial origin. Dual neutron and gamma imagi ng is also of prime interest for nuclear safety and security applications. In this context\, we have designed and patented a innovative dual neutro n and γ-ray imaging tool\, so-called GN-Vision\, that aims at addressing the most relevant challenges for the aforementioned applications. The syst em consists of a compact and handheld-portable device capable of measuring and simultaneously imaging γ-rays and slow – thermal to 100 eV – neu trons.\n\nThe GN-Vision device follows the design of the previous i-TED de tector [1]\, an array of Compton cameras based on large monolithic positio n sensitive LaCl3(Ce) crystals that were initially designed for neutron-ca pture experiments at CERN [2]. Moreover\, the applicability of i-TED to ra nge verification in ion beam therapy [3\, 4] and imaging-based dosimetry i n BNCT [5\, 6] has been explored with promising results. In addition to i- TED\, GN-Vision exploits a neutron-gamma discriminating detector together with a passive collimator to achieve neutron imaging\, while keeping the C ompton imaging of γ-rays [7].\n\nFollowing the conceptual demonstration o f the simultaneous neutron and gamma-ray imaging in a first Monte Carlo st udy [7]\, we have been working at IFIC in the technical implementation of the first prototype. In this contribution we will present the development and characterization of a position-sensitive CLYC detector that acts as th e neutron imaging layer and γ-ray Compton scatterer of the dual γ-ray an d neutron imaging system GN-Vision. The succesful implementation of the po sition-senstivite neutron-gamma discrimination capability has layed the fo undations for the first proof-of-concept experiment of the neutron imaging capability [8]\, that will be presented in this talk. Last\, the contribu tion will cover the future prospects\, including the studies on the optimi zation of the collimation system\, the advances towards the neutron and ga mma imaging integration\, the expected performance of the complete GN-Visi on device and the plans for upcoming field test-measurements.\nReferences \n[1] C.

The interactions of these protons with tissues or materials generate se condary neutrons that pose a risk of irradiation. The dosimetry of these n eutrons must be measured accurately\, and it must be monitored to minimize the risk of apparition of secondary cancers in patients\, and also to pro tect the exposed workers.\n\nTwo CLYC-based neutron dosimeters have been d esigned and fabricated at CIEMAT\, with the aim of assessing their applica tion to neutron dosimetry. Cs$_2$LiYCl$_6$:Ce (CLYC) detectors are inorgan ic scintillators with excellent gamma-neutron discrimination properties. T he detector takes advantage of the high enrichment of $^6$Li for the detec tion of thermal neutrons\, via the $^6$Li(n\,$\\alpha$) reaction. It is al so sensitive to fast neutrons\, when used in combination with polyethylene moderators and via nuclear reactions like the $^{35}$Cl(n\,p). The two de vices were characterized at CIEMAT’s Neutron Standards Laboratory (LPN)\ , showing a good agreement with the expected behavior predicted by Monte C arlo simulations.

In both cases\ , a commercial WENDI-II extended range dosimeter\, based on a $^3$He count er\, was used as a reference.\n\nCLYC detectors have similar efficiencies than equivalent sized $^3$He-based detectors and a significantly faster ti me response\, which makes them good candidates for neutron dosimetry in pr oton therapy FLASH treatments.\n\nhttps://indico.ific.uv.es/event/7664/con tributions/25515/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25515/ END:VEVENT BEGIN:VEVENT SUMMARY:Irradiation of in vitro cell cultures with a laser-driven proton s ource DTSTART;VALUE=DATE-TIME:20241119T142200Z DTEND;VALUE=DATE-TIME:20241119T143200Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25513@indico.ific.uv.es DESCRIPTION:Speakers: Alicia Reija ()\nPurpose: The dose per fraction\, th e dose rate and the delivery time in radiation therapy are key parameters to understand both the efficacy of the treatment and the level of radiatio n toxicity in normal tissue. Laser-driven sources are known for their brig htness and short pulse duration\, and these characteristics offer the poss ibility to study the biological effects of pulsed radiation beams operatin g at peak dose rates that are orders of magnitude larger than those achiev ed in conventional accelerators. Given that these sources can reach a cert ain dose per pulse\, the FLASH effect could be potentially triggered. In this work we investigate the response of in vitro cell cultures to laser-d riven\, low-energy protons.\nMaterials and Methods: A set of 27 in vitro A 549 cell cultures has been irradiated with low energy protons driven by th e VEGA-3 laser beamline available at the Spanish Pulsed Laser Center. The cells were grown in a sterile flask sealed with a thin polyethylene window to reduce energy attenuation. The laser pulses (27 J\, 200 fs) were focus ed onto thin aluminum foils installed on a multishot target system develop ed at the University of Santiago de Compostela. Since the resulting proton spectrum has a Maxwellian-like broad distribution\, a magnetic energy sel ector was developed to obtain quasi-monoenergetic proton beamlets. These b eams were driven in air through a thin Kapton window\, and the proton spec trum was characterised using a Thomson parabola and a TOF detector. The do se delivered to the cells was evaluated with unlaminated RCF. \nResults: T he selected proton energy for cell irradiation was 5 MeV. The preliminary results of the dose evaluation show an average dose per pulse of 100 mGy\ , with low shot-to-shot variability. Cells were irradiated at 3\, 5 and 8 Gy in duplicate to perform radiobiological studies evaluating cell prolife ration and clonogenicity. Despite inconclusive findings from the cell prol iferation curves\, the colony formation assays exhibited a pronounced expo nential decrease in cell survival fraction correlated with the administere d dose. These findings will be compared with those achieved in a similar e xperiment performed with laser-driven x-rays\, and with a conventional MV Linac. \nConclusions: We have tested the feasibility of cell proliferation and colony formation assays with in vitro cell cultures using laser-drive n protons in an experimental campaign which\, on a national level\, has be en the first one combining laser-driven ion sources with biological resear ch.\n\nhttps://indico.ific.uv.es/event/7664/contributions/25513/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25513/ END:VEVENT BEGIN:VEVENT SUMMARY:Low Earth Orbit compact Neutron detector DTSTART;VALUE=DATE-TIME:20241119T154200Z DTEND;VALUE=DATE-TIME:20241119T155200Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25520@indico.ific.uv.es DESCRIPTION:Speakers: Luis Caballero (IFIC (CSIC/UV))\nThe PoliTech-1 miss ion consists of a nanosatellite that includes various payloads\, among whi ch is the LEON system (Low Earth Orbit compact Neutron detector).

To meet the requirements for FLASH\, ultra-intense pulsed beams—dose rates exceeding 40 Gy/s—must be achieved. This has c reated the need to develop facilities capable of conducting experiments at sufficiently high rates as well as detectors with the potential of correc tly measuring the accumulated dose.. \nIn this work we investigate the res ponse of SiC p-n diodes\, with a 30-micron diameter and a nominal thicknes s of 3 microns\, developed at IMB-CNM (CSIC) to low-energy pulsed proton b eams and ultra-high accumulated doses. The experiments were conducted with 1 MeV and 2 MeV proton beams at the 3 MV Tandem accelerator of the Nation al Accelerator Center (CNA) using a custom-built pulsed beam system. \nIt was demonstrated that the CNA can irradiate under Ultra High Dose Rate (UH DR) conditions\, with pulse durations on the order of microseconds (~μs)\ , achieving dose rates of up to 10 kGy/s\, dose-per-pulse values of 5.6 Gy \, and dose rate-per-pulse of 4.6 MGy/s.\nThe results indicate that the se nsors response degrades for doses between 70 and 800 kGy\, after which a p lateau is reached. Once this plateau is achieved\, the sensors exhibit a l inear response over the entire range of dose rates tested\, up to doses of at least 5 MGy.\n\nhttps://indico.ific.uv.es/event/7664/contributions/255 04/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25504/ END:VEVENT BEGIN:VEVENT SUMMARY:PN-pairing with Gogny interaction and Taurus code DTSTART;VALUE=DATE-TIME:20241120T090000Z DTEND;VALUE=DATE-TIME:20241120T091500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25497@indico.ific.uv.es DESCRIPTION:Speakers: Miguel de la Fuente (UAM)\nhttps://indico.ific.uv.es /event/7664/contributions/25497/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25497/ END:VEVENT BEGIN:VEVENT SUMMARY:Analysis of semi-inclusive neutrino scattering within the relativi stic distorted wave approach DTSTART;VALUE=DATE-TIME:20241120T100000Z DTEND;VALUE=DATE-TIME:20241120T101500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25481@indico.ific.uv.es DESCRIPTION:Speakers: Juan Manuel Franco (Instituto de Física Corpuscular (IFIC))\nNuclear effects in neutrino-nucleus scattering are one of the ma in sources of uncertainty in the analysis of neutrino oscillation experime nts. Due to the extended neutrino energy distribution\, very different rea ction mechanisms contribute to the cross section at the same time. Measure ments of muon momentum in CC0π events are very important for experiments like T2K\, where most of the information about the oscillation signal come s from detection of the final-state muons only. However\, those inclusive measurements make difficult to distinguish the contributions of nuclear ef fects. For instance\, they do not allow to separate between different nucl ear models and are not sufficient to put constraints on the amount of two- body current contributions. This is the reason why there is a growing inte rest in measurements of more exclusive processes\, for instance the detect ion in coincidence of a muon and an ejected proton in the final state. Int erpretation of such reactions\, usually called semi-inclusive reactions\, is challenging as it requires realistic models of the initial nuclear stat e and an appropriate description of proton final-state interactions.\n\nIn this talk we're going to present the theoretical predictions of semi-incl usive νμ cross sections on $^{12}$C and $^{40}$Ar obtained within an unf actorized approach based on the relativistic distorted wave impulse approx imation (RDWIA) and compare them with T2K\, MINERνA and MicroBooNE measur ements and predictions of the inclusive SuSAv2-MEC model implemented in th e neutrino event generator GENIE.\n\nhttps://indico.ific.uv.es/event/7664/ contributions/25481/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25481/ END:VEVENT BEGIN:VEVENT SUMMARY:Thermal neutrons at HiSPANoS: Proposal for a moderating system DTSTART;VALUE=DATE-TIME:20241120T101500Z DTEND;VALUE=DATE-TIME:20241120T103000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25482@indico.ific.uv.es DESCRIPTION:Speakers: Jesús Bartolomé Sarsa (CNA\, Universidad de Sevill a)\nThe use of thermal neutron radiation is widespread across numerous fie lds and its use is a core component of many different experiments\, includ ing the study of fission and fusion\, archeology\, astrophysics\, medicine or research applications.

Many of these nuclei can be approxi mately described by a model consisting of an inert core and one or more va lence nucleons. For some of these nuclei\, the quadrupole deformation is e specially relevant and should be included in the structure models. This is the case of $^{11}\\text{Be}$ and $^{17}\\text{C}$\, which can be approxi mately described as a core and a weakly-bound neutron. \n\nTwo different d eformed two-body models have been used to described these nuclei\, and the ir results have been compared [Phys. Rev. C 108 (2023) 024613]: the semi-m icroscopic particle-plus-AMD (PAMD) model from [Phys. Rev. C 89 (2014) 014 333] and the Nilsson model. We now explore a new model built as a combinat ion of these two. Furthermore\, Pauli blocking effects of deformed single- particle Nilsson states are considered\, applying the Bardeen–Cooper–S chrieffer (BCS) formalism. The bound states wavefunctions obtained for $^{ 17}\\text{C}$ have been tested by applying them to the $^{16}\\text{C}(d\, p)^{17}\\text{C}$ transfer reaction\, using as reaction framework the Adia batic Distorted Wave Approximation (ADWA). The results are consistent with the data from [Phys. Lett. B 811 (2020) 135939]\, Pauli blocking effects significantly improve the agreement.\n\nIn our calculations\, the continuu m spectrum of the weakly-bound nuclei is discretized using the transformed harmonic oscillator basis (THO) [Phys. Rev. C 80 (2009) 054605]. The THO has been successfully applied to the discretization of the continuum of tw o-body and three-body weakly bound nuclei for the analysis of break up and transfer reactions [Phys. Rev. Lett. 109 (2012) 232502\, Phys. Rev. C 94 (2016) 054622]. Therefore\, our structure models can be used to study proc esses such as transfer to the continuum or Coulomb dissociation.\n\nhttps: //indico.ific.uv.es/event/7664/contributions/25486/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25486/ END:VEVENT BEGIN:VEVENT SUMMARY:New experimental measurements for Ba to Nd nuclei (A$\\sim$160) fo r r-process rare-earth nucleosynthesis DTSTART;VALUE=DATE-TIME:20241120T080000Z DTEND;VALUE=DATE-TIME:20241120T081500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25487@indico.ific.uv.es DESCRIPTION:Speakers: Max Pallàs Solís (Universitat Politècnica de Cata lunya (UPC))\nThe r-process\, also known as the rapid neutron capture proc ess\, plays a crucial role in the formation of more than half of the eleme nts that are heavier than iron.

More precisely\, Morinaga [1] proposed a particular alpha cl uster configuration known as the linear-chain cluster state (LCCS)\, in wh ich the alpha particles are arranged in a linear sequence. In this configu ration\, the neutron excess appears to play a significant role in stabiliz ing the structure. Suhara and Kanada-En'yo [2] were the first to predict t he existence of the LCCS in $^{14}$C using antisymmetrized molecular dynam ics (AMD). However\, it was not until 2014 that the first experimental evi dence was obtained by Freer *et al.* [3]\, supporting the idea of the LCCS in $^{14}$C by identifying the prolate band (J$^{\\pi}$ = $0^+$\, $2^+$\, 4$^+$). Two years later\, Fritsch *et al.* [4] observed the 2$^+$ and the 4$^+$ states\, but the position of the band head (0$^+$) remained unknown . Recently\, Yamaguchi *et al.* [5] reported having identified this 0$^+$ state at 3 MeV\, however\, a recent work has challenged this finding [6].\ n\nThe alpha-cluster structure of $^{14}$C has been investigated through t he resonance scattering in the $^{10}$Be($^{4}$He\,$^{4}$He)$^{10}$Be reac tion. The experiment was conducted using an active target time projection chamber (AT-TPC) filled with pure He\, placed inside the solenoidal spectr ometer SOLARIS [7]. The standalone $^{10}$Be beam was injected into the Re A6 accelerator at the Facility for Rare Isotope Beams (FRIB)\, where it wa s accelerated and subsequently delivered to SOLARIS. Different gas pressur es inside the AT-TPC and different beam energies were used in order to ext ract as much information as possible about the different LCCS bands: the $ \\pi$-bond and the $\\sigma$-bond. Both bands will be studied using a new observable: the three-particle decay inelastic channel branching ratio.\n\ n\n\n[1] H.

This phenomenon\, known as shape coexistence\, is widespread across th e nuclear chart and it provides a crucial role in understanding nuclear st ructure [1]. \n\nIn our study we complement shell-model calculations [2] w ith beyond-mean-field Hartree-Fock-Bogoliubov techniques [3] to shed light on the rich coexistence of differently deformed structures. We infer shap e coexistence from multiple observables such as: collective wavefunctions\ , quadrupole moments\, shape invariants\, and $E0$ transitions. The combin ation of all these hints allows us to understand the complexities of shape coexistence and the notion of nuclear shape itself [3].\n\nFor instance\, $^{28}$Si presents a competition between the oblate ground state and the excited prolate rotational band ($6.5$ MeV)\, with a possible superdeforme d structure at higher energies ($\\sim10$-$20$ MeV).

The s tellar characteristics of a neutron star are strongly affected by baryonic interactions. Constraints from experimental observations of heavy ions sh ow remarkable consistency with astrophysical measurements and provide comp lementary information at intermediate densities. In this respect\, the pro duction of exotic hypernuclei in ion-induced reactions is expected to add precise observables at higher densities than those obtained in previous ex periments. \nThe WASA-FRS HypHI Experiment focuses on the study of light h ypernuclei by means of heavy-ion\ninduced reactions in 6Li collisions with 12C at 1.96GeV/u. It is part of the WASA-FRS experimental campaign\, and so is the eta-prime experiment [1]. The distinctive combination of the hig h-resolution spectrometer FRS [2] and the high-acceptance detector system WASA [3] is used. The experiment was successfully conducted at GSI-FAIR i n Germany in March 2022 as a component of the FAIR Phase-0 Physics Program \, within the Super-FRS Experiment Collaboration. The primary objectives o f this experiment are twofold: to shed light on the hypertriton puzzle [4] and to investigate the existence of the previously proposed nnΛ bound st ate [5]. Currently\, the data from the experiment is under analysis.\nPart of the data analysis is to provide a precise ion-optics of the measuremen t of the fragment orignated from the mesonic weak decay of the hypernuclei of interest. The reconstruction the ion-optics of fragments is based on t he calibration run of FRS optics. We have proposed to implement machine le arning models and neural networks to represent the ion-optics of FRS: Whil e the current state of the problem involves solving equations of motion of particles in non-ideal magnetic fields - which leads to the application o f approximations in the calculations - the implementation of artificial in telligence models allows us to obtain accurate results with possible bette r momentum resolution.\nIn this presentation\, we will present the current status of the R&D in machine learning model of the ion-optics and the pro spect of the inference of the measured momentum of the fragments based on the calibration data recorded during the WASA-FRS experimental campaign of 2022.\n[1] Y.K.

Currently\, many experimental a nd theoretical efforts are dedicated to investigating this region of the n uclear chart [1-5]\, aiming to comprehend the robustness of nuclear shells far from stability and the emergence of collective effects as nucleons ar e added. The interaction among valence nucleons may be capable of attenuat ing the magic nature of a nucleus very close to shell closures [6]. From t his perspective\, isotopes of Ge\, with $Z = 32$\, could be of significant interest to understand the evolution of the $N = 50$ gap.\n\nThis work fo cuses on the experimental and theoretical study of $^{84}\\mathrm{Ge}$\, w ith $Z = 32$ and $N = 52$. Although its excited structure has been previou sly attempted to be studied\, it is not well established [2\, 3\, 7]. Thi s study takes advantage of the good production and high purity of exotic n uclei $^{85\,84}\\mathrm{Ga}$ at the ISOLDE facility at CERN to populate t he structure of $^{84}\\mathrm{Ge}$ through $\\beta^-n$ and $\\beta^-$ dec ay [8]. High-resolution gamma spectroscopy is employed to investigate the excited structure\, based on the gamma-gamma coincidences technique. In ad dition\, two theoretical studies are proposed. One of them is based on the Interacting Shell Model [9\, 10]\, aiming to observe the nucleus structur e and the filling of single-particle levels\, and compare with the experim ental results. The other theoretical study complements the former\; it is a beyond-mean-field study using the Projected Generator Coordinate Method to evaluate low-energy collective effects [11\, 12].\n\n\n**References**\n \n[1] M.

Re cently\, the more exotic i-process\, which involves higher neutron densiti es and more exotic nuclei than the s-process [2]\, is also gaining great i nterest. \n\nOne of the best suited methods to measure neutron capture (n\ ,γ) cross sections over the full stellar range of interest is the time-of -flight (TOF) technique. However\, TOF neutron capture measurements on s-p rocess branching isotopes are very challenging due to the limited mass (~m g) available and the high experimental background arising from the sample activity [3]. The situation has improved in recent years with the combinat ion of facilities with high instantaneous flux\, such as the n_TOF-EAR2 fa cility\, with detection systems with an enhanced detection sensitivity and high counting rate capabilities [4\,5\,6]. In this context\, this contrib ution will present a brief summary about recent improvements at the n_TOF facility and some highlights of TOF measurements of key isotopes.\n\nDespi te the significant progresses\, the TOF technique is still not capable to adress the neutron capture cross section of many key unstable isotopes [3\ ,7]. And for others\, it did not suceed to provide data over the complete neutron-energy ranges in order to derive direct information of astrophysic al interest [8\,9\,10]. In this context\, complementing the TOF technique with activation measurements in a quasi-stellar beam\, when feasible\, may deliver complementary and more accurate information on a specific cross s ection [8]. Moreover\, the unsurpassed sensitivity of activation measureme nt opens the door to first-time measurements on much smaller sample quanti ties [7]. Following this logic\, n_TOF has recently deployed the new high- flux n_TOF-NEAR activation station [11]. An overview will be given on rece nt activities and plans at the NEAR facility\, including the development o f CYCLING\, a cyclic ativation station for (n\,g) measurements. Last\, fut ure perspectives for neutron capture measurements CERN will also be briefl y discussed\, such as the possibilities of the ultra high-luminosity BDF n eutron source and the synergic cooperation with ISOLDE to produce unstable targets. \n\n**References**\n[1] F.

Th is transition is closely linked to shape coexistence [2]\, a phenomenon wh ere two or more states with different intrinsic shapes coexist within the same nucleus at low excitation energy and within a narrow energy range. Sp ecifically\, the abrupt change arises from the inversion of two distinct q uantum configurations of nucleons\, each corresponding to different nuclea r shapes. These shifts are interpreted as quantum phase transitions [3]\, indicating a fundamental transformation in nuclear properties. This phase transition emphasizes the importance of nuclear deformations and the vari ety of shapes present in neutron-rich nuclei such as strontium and zirconi um.\n\nIn the case of $^{100}$Sr (N=62)\, once shape inversion occurs at N =60\, intruder states play a crucial role in understanding the structural evolution of the nucleus. These states refer to configurations where nucle ons follow an orbital occupancy order that does not align with the predict ions of the spherical shell model\, underscoring the importance of deforma tion and collective effects.\n\nTo investigate shape transitions and nucle ar structure in $^{100}$Sr\, an experiment was conducted at the ISOLDE Dec ay Station (IDS) [4]\, populating their excited states via the beta decay of $^{100}$Rb. The fast-timing method [5]\, particularly through the use o f γ-γ coincidences\, enables the measurement of half-lives of excited st ates on the order of tens of picoseconds. A versatile detector system was employed\, consisting of high-purity germanium (Clover-type) detectors for precise gamma-ray identification\, plastic scintillators for beta particl e detection\, and LaBr$_{3}$(Ce) crystals\, valued for their superior time resolution in measuring excited-state lifetimes. \n\nThis contribution pr esents new half-life measurements that resolve discrepancies from previous values and provide new insights into the nuclear structure of neutron-ric h nuclei in the N≈60 region\, furthering the understanding of the shape deformation phenomenon.\n\n[1] R.

In 2022\, a new state-of-the-art (n\,γ) experimental setup was commi ssioned at n_TOF EAR2 [Weiss15]\, consisting of an array of nine sTED unit s [Alc24] arranged in a cylindrical configuration close to the target\, tw o conventional large-volume C6D6 detectors\, and one LaCl₃(Ce) detector [Bal23a\,Ler23]. This setup enabled a significant improvement in terms of detection sensitivity and covered neutron-energy range.\n\nFurther improve ments could be attained with the use of a new scintillation material repla cing the liquid C6D6. Recent advancements in solution-growth methods for t rans-stilbene crystals have enabled the production of high-purity deuterat ed stilbene (stilbene-d12) crystals. With their favorable properties with respect to liquid C6D6\, such as higher density\, excellent n/γ discrimin ation\, larger light yield\, and reduced chemical risks\, deuterated stilb ene presents a promising alternative to liquid C6D6 scintillators. Their s olid-state form allows for thinner encapsulation\, eliminates the need for expansion volumes\, and removes the requirement for a borosilicate quartz window for optical coupling. Additionally\, they can be more easily coupl ed to photosensors\, thereby facilitating the use of Silicon photomultipli ers and further reducing the material budget per detector. These factors c ontribute to lowering the intrinsic neutron sensitivity of the detection d evice\, thereby enhancing systematic accuracy in nuclei or neutron energy regions where elastic scattering dominates. Such developments will enable superior detection sensitivities in radiative neutron-capture cross-sectio n measurements and they will open the possibility for (n\,n) and (n\,n’) measurements over broad neutron-energy ranges and will reduce neutron-ind uced backgrounds [Bal23b]. \nDriven by this motivation\, we present a conc eptual design study for a future Stilbene-d12 Detector Array\, referred to as STAR\, primarily aimed at (n\,γ) measurements of very small and/or ra dioactive samples at CERN n_TOF EAR2. Conceptualization\, MC design and In itial experimental results with a stilbene prototype will be presented at the time of the workshop.\n\n[Alc24] V.

The first empirical observation of this behaviour came f rom experimental measurements of the interaction cross-section for neutron -rich nuclei\, specifically the scattering cross-section of Lithium isotop es. As the number of neutrons approached the dripline\, the interaction ra dius deviated from theoretical predictions\, with $^{11}$Li being the most noticeable case [1]. This discovery was interpreted as a new type of nucl ear structure [2]\, formed by a compact core and an external set of nucleo ns. This hypothesis was confirmed a few years later in $^{11}$Li break-up experiments [3].\n\n$^{11}$Li can be considered the archetype of a two-neu tron halo: a three-body system formed by two weakly correlated neutrons lo osely bound to the $^9$Li ground state (g.s.) [4]. Despite being intensive ly studied for a long time\, there are still open questions regarding the structure of $^{11}$Li. While the g.s. is known to be a mixture of p ($59( 1)\\%$)\, s ($35(4)\\%$)\, and d ($6(4)\\%$) waves [5]\, knowledge of high er-energy resonant states (no excited states are bound in $^{11}$Li) is no t well settled\, as different reaction studies give different results.\n\n The low-lying continuum spectrum of $^{11}$Li is dominated by broad dipol e structures observed in several experiments\, while narrower resonances h ave been proposed up to 6.2 MeV. Recent results on the low-lying continuum structure in $^{11}$Li have been obtained from inelastic p- and d-scatter ing at TRIUMF [6\,7]. The elastic cross-sections obtained from both experi ments are consistent\; however\, the inelastic scattering results indicate d a resonant state at 0.80(4) MeV\, $\\Gamma=1.15(6)$ MeV for proton inela stic scattering [7]\, and this same resonance was characterized to be at 1 .03(4) MeV\, $\\Gamma=0.51(11)$ MeV with deuteron scattering [6]. However\ , a more relevant question concerns the physical process involved: excitat ion to resonance or direct excitation to the continuum?\n\nMost experiment s that explore the excited structure of $^{11}$Li start from $^{11}$Li g.s \, which is promoted to excited levels. The only exception is the study of the (very complex) $^{14}$C($\\pi^-$\,p+d) reaction [8]\, whose results w ere limited by low resolution. The MAGISOL collaboration has performed an experiment\, IS690 [9]\, intending to probe the excited structure of $^{11 }$Li through an alternate approach: populate directly the excited states o f $^{11}$Li using a two-neutron transfer reaction $^9$Li(t\,p)$^{11}$Li\, and obtain information of the excited states through the momentum distribu tion of the residual proton. This experiment complements the $^{11}$Li(p\, t)$^9$Li experiment carried out at TRIUMF [10]\, additionally\, knowledge of the elastic scattering channel can be employed to fix optical potential s in the theoretical models. \n\nIS690 took place at the Scattering Experi mental Chamber (SEC) in the HIE-ISOLDE facility at CERN between the 14th a nd 22nd of October 2024. A post-accelerated 7 MeV/u $^9$Li beam was imping ed on a $^3$H target ($^3$H absorbed in a thin Ti-foil at a ratio of $\\si m$0.4/1). The energy of the incoming $^9$Li beam\, 7 MeV/u\, was chosen to facilitate the 2n transfer while reducing the number of additional open c hannels. An upgraded detection setup was prepared to detect the emitted pr otons from the $^9$Li(t\,p)$^{11}$Li reaction and distinguish them from ba ckground reactions\, especially $^9$Li(p\,d)$^{10}$Li and elastic channels \, as well as protons from Ti(t\,p). The setup offered optimal angular cov erage and consisted of three detector structures: (a) five particle telesc opes (DSSD+PAD) forming a pentagon around the target\, (b) a frontal teles cope formed by two S3-CD detectors\, and (c) a backward S5 detector to det ect backward protons.\n\nIn this contribution\, we will give an overview o f the experiment and a summary of the (very recent) data obtained\, along with our preliminary analysis.\n\n\n\n**References**\n \n\n 1.

The facility uses a high-inten sity neutron source\, a large lead spallation target coupled with the CERN -PS 20 GeV/c proton beam\, and features three experimental areas: Experime ntal Area 1 (EAR1)\, located approximately 185 meters horizontally from th e spallation target\; Experimental Area 2 (EAR2)\, positioned vertically a round 20 meters from the target\; and the newly established NEAR station\, located about 3 meters from the target and currently in the commissioning phase.\nSince the beginning of the n_TOF collaboration\, CIEMAT has been engaged in capture measurements relevant to nuclear technologies. Over rec ent years\, we have been focused on developing new detectors and conductin g capture measurements for various isotopes.\nIn the area of detector deve lopment\, the sTED detector was constructed and commissioned in 2023 at EA R2\, initially with 9 modules. A planned upgrade of the sTED detector to 2 7 modules is scheduled for construction in 2025\, which will significantly enhance the setup’s efficiency. Additionally\, a comprehensive validati on of the C$_6$D$_6$ detectors used at n_TOF was completed last year\, dem onstrating that the new C$_6$D$_6$-Legnaro detectors exhibit a notably imp roved response. Consequently\, further units of these detectors will be ac quired to optimize measurement capabilities.\nIn recent years\, several ne utron capture cross-section measurements have been conducted in EAR1 using C$_6$D$_6$ detectors. These include studies on Tantalum\, relevant for sp ace nuclear reactors\; $^{167}$Er\, considered as a burnable absorber for nuclear reactors\; and $^{238}$U\, a major component in light water reacto rs.

Accordingly\, there i s a renewed interest in measuring the yields and energy spectra of (alpha\ ,n) reactions on many isotopes (see. Ref. [1] for a recent overview of the scientific cases and a summary of the reactions of interest in the mentio ned fields of research). In this context\, the Spanish experimental nuclea r physics community has established the MANY (Measurements of Alpha-N Yiel ds) Collaboration to measure (alpha\,n) reactions at two different acceler ator facilities (CNA HiSPANoS [2\,3] and CMAM [4]) using three complementa ry detectors for assessing the corresponding neutron yields (miniBELEN [5] and GARY [6]) and energy spectra (MONSTER [7]).\n \nThe CNA HiSPANoS faci lity is driven by a 3 MV tandem accelerator delivering both continuous and pulsed (2% duty cycle) beams of proton/deuteron up to 6 MeV and alphas up to 9 MeV. The current source of alphas is a NEC-ALPHATROSS model deliveri ng a maximum current of only 2 uA\, and the pulsing systems is only design ed and optimized for protons and deuterons\, hence performing poorly for a lpha beams. This configuration is well suited for activation and neutron c ounting experiments with miniBELEN\, which shall start in early 2025\, and the results from preliminary measurements on 27Al(alpha\,n) by ToF using the pulsed beam and a single MONSTER neutron detector module are promising .

MYRRHA is an experimental A ccelerator Driven System that uses a lead-bismuth mixture as a coolant sys tem. The radiological burden associated with the use of this type of coola nt for fast nuclear systems is mainly due to the production of 210Po from 209Bi(n\,γ) reactions. There are significant discrepancies in the existin g evaluations of 209Bi(n\,γ) reactions\, particularly concerning the feed ing into the metastable state. Therefore\, accurate prediction of the 210P o inventory in lead-bismuth cooled nuclear systems requires precise knowle dge of both reaction channels and their branching ratios.\n\nFrom an astro physical perspective\, this reaction also plays a crucial role in the s-pr ocess and for U/Th cosmic clocks.\n\nThe most recent 209Bi(n\,γ) Time-of- Flight (ToF) measurement was performed at the CERN n_TOF EAR1 facility by C. Domingo and colleagues in 2006\, using the state-of-the-art low neutron sensitivity C6D6 detectors. However\, the target accuracy could not be re ached due to a significant in-beam γ-ray background and insufficient lumi nosity of EAR1. This limitation has been significantly improved with the r enewed high luminosity EAR2. Recently\, in combination with the high sensi tivity sTED array detection setup\, EAR2 has demonstrated its potential fo r challenging (n\,γ) such as 94Nb and 79Se cross section measurements in a broad neutron energy range. \n\nThe current 209Bi(n\,γ) experiment at n _TOF EAR2 aims to achieve an accuracy of 5-10% in the Resolved Resonance R egion\, covering neutron energies from thermal levels up to 35 keV\, and a n accuracy of less than 15% in the neutron energy range from 35 to 100 keV . At the time of the conference\, a comprehensive overview of the ongoing experiment at the CERN n_TOF facility will be presented\, along with the i nitial experimental results from the current measurement campaign.\n\nhttp s://indico.ific.uv.es/event/7664/contributions/25490/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25490/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of WASA-FRS HypHI Experiment: Study of light hypernuclei at GSI-FAIR DTSTART;VALUE=DATE-TIME:20241119T143000Z DTEND;VALUE=DATE-TIME:20241119T144500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25489@indico.ific.uv.es DESCRIPTION:Speakers: Samuel Escrig López (Instituto de Estructura de la Materia (IEM-CSIC))\nThe WASA-FRS HypHI Experiment focuses on the study of light hypernuclei by means of heavy-ion induced reactions. It is part of the WASA-FRS experimental campaign\, and so is the Eta-prime Experiment [1 ]. The distinctive combination of the high-resolution spectrometer FRS [2] and the high-acceptance detector system WASA [3] is used. The experiment was successfully conducted at GSI-FAIR in Germany in March 2022 as a compo nent of the FAIR Phase-0 Physics Program\, within the Super-FRS Experiment Collaboration. Currently\, the data from the experiment is under analysis .\n\nIn this experiment\, the production of the hypernuclei is achieved by bombarding a diamond target with a 6Li beam at 1.96 GeV/u. In this collis ion\, Λ hyperon can merge with the nuclear fragment\, forming a hypernucl eus. The production of hypernuclei in the spectator rapidity region\, with a similar velocity of the incident beam\, allows for the in-flight study of the hypernuclei behind the target material. The hypernuclear events are identified by detecting both the residual nuclei and the π- particles em itted from the mesonic weak decay of the hypernuclei.\n\nThe second half o f the FRagment Separator FRS serves as a high-resolution spectrometer for measuring the decay fragments. Additionally\, the Wide Angle Shower Appara tus (WASA)\, placed in the mid-focal plane of the FRS\, is employed for tr acking the decay π- particle. The WASA system consists of a superconducti ng magnet and a group of detectors\, including a drift chamber of several layers of strawtubes and plastic scintillator barrel and walls. The hypern ucleus is subsequently reconstructed\, and its properties\, such as invari ant mass and lifetime\, are analysed.\n\nThe primary objectives of this ex periment are twofold: to shed light on the hypertriton puzzle [4] and to i nvestigate the existence of the previously proposed nnΛ bound state [5]. Firstly\, the significantly shorter hypertriton lifetime reported by three independent state-of-the-art experiments\, namely ALICE [6]\, STAR [7]\, and HypHI [8]\, compared to the predictions of theoretical models remains poorly understood. Therefore\, obtaining new accurate results for the inva riant mass and lifetime of 3ΛH (and 4ΛH) is crucial to reach a definitiv e conclusion. Secondly\, the observed enhancement in the invariant mass di stributions of the d+π- and t+π- final states\, as reported by the HypHI Collaboration [5]\, cannot be accounted for by existing theoretical calcu lations\, which indicate the absence of a neutral nnΛ bound state. Conseq uently\, the WASA-FRS HypHI Experiment aims to produce more precise and st atistically significant experimental results that can provide clarificatio n on the potential existence of nnΛ.\n\nMy contribution to the conference will provide an overview of the WASA-FRS HypHI Experiment\, including its objectives and methodology. Details of the experiment approach that combi nes for the first time a cylindrical detection system with a fragment sepa rator will be presented. I will also discuss the current state of the expe riment analysis\, emphasizing the GNN implementation for particle tracking and the ion-optics calibration. Finally\, I will show the first prelimina ry results of the invariant mass of Λ and 3ΛH.\n\n[1] Y.K. Tanaka *et al .*\, J. Phys. Conf. Ser. **1643** (2020) 012181.\n[2] H. Geissel *et al.*\ , Nucl.

To address this need\, a new experimental campaign has been performed at n\\_TOF\, th e time-of-flight facility of CERN\, measuring $^{239}$Pu for the first tim e at this facility. This work is part of the scientific program supported by the European Commission H2020 initiative\, *Supplying Accurate Nuclear Data for energy and non-energy Applications* (SANDA).\n\nIn this experimen t\, ten extremely pure $^{239}$Pu samples\, produced at the European JRC-G eel target laboratory\, with a total mass of less than 10 mg were placed i n a novel ionization chamber specifically designed to handle the high coun ting rates caused by the $\\alpha$-decay of $^{239}$Pu.

Universidade de Santiago de Compostela (U SC))\nNuclear Physics experiments are usually carried out in large acceler ators\, whose reduced number restricts the access to these facilities. For this reason\, there is a growing interest in developing complementary fac ilities capable of hosting Nuclear Physics experiments\, even at smaller s ize\, to further extend the nuclear data available. In this context\, high -power\, high-repetition-rate lasers become an appealing complement due to the reduced footprint and lower running costs.\n\nAs a proof-of-concept\, a photoactivation experiment of $^{209}$Bi was carried out using the 150 TW arm of the DRACO laser (HZDR\, Germany). Electron bunches of ~0.1 nC an d energy up to 450 MeV were accelerated at 0.1 Hz via the laser wakefield acceleration (LWFA) mechanism and propagated into a thin tantalum converte r to obtain the high energy bremsstrahlung photons that were used for phot oactivation. After 1 hour of irradiation\, corresponding to 370 shots\, a short-lived activity of 10-100 Bq was produced\, and photoactivation react ions below the pion threshold of up to at least $^{209}$Bi(γ\,9n)$^{200}$ Bi were observed\, with activation levels in agreement with numerical simu lations. The direct production of lighter elements\, such as Pb or Tl\, wa s also studied\, finding that it is comparable to that of the parent bismu th nucleus.\n\nThese results show not only the potential of laser-driven a ccelerators as a useful tool in Nuclear Physics\, but also the possibility of measuring offline the high-energy photon spectrum from the activation yield\, with the advantage of being insensitive to pulse pile-up and the s trong electromagnetic pulse accompanying the laser shots.\n\nhttps://indic o.ific.uv.es/event/7664/contributions/25493/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25493/ END:VEVENT BEGIN:VEVENT SUMMARY:Measurement of 27Al(alpha\,n)30P reaction cross-section at CMAM us ing the miniBELEN neutron counter DTSTART;VALUE=DATE-TIME:20241119T134500Z DTEND;VALUE=DATE-TIME:20241119T140000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25494@indico.ific.uv.es DESCRIPTION:Speakers: Nil Mont i Geli (Universitat Politècnica de Catalun ya)\nThe production of neutrons through α-induced reactions play an impor tant role in fields such as nuclear astrophysics\, underground laboratorie s\, fission and fusion reactors and non-destructive assays for non- prolif eration and spent fuel management applications.

Tengblad\, for the ISRS collaboration.\n\nAbstract \n \nThe HIE-ISOLDE facility accelerates a unique worldwide variety of radioa ctive ions up to collision energies close to 10 MeV/A. The physics program covers a broad range of nuclear structure studies\, from shell-evolution to nuclear astrophysics. The ISOLDE Superconducting Recoil Separator (ISRS ) [1\, 2] will extend HIE-ISOLDE physics by providing unprecedented mass s electivity for in-beam and focal-plane spectroscopy. ISRS is an array of i ron-free superconducting multifunction magnets\, cooled by cryocoolers\, i ntegrated into a compact Fixed-Field Alternating Gradient (FFAG) particle storage ring where A/Q selectivity is achieved by combining the fragment c yclotron frequency and RF extraction with ToF and particle identification at the focal plane [3]. The ISRS collaboration has recently launched a R&D program funded by Spain. The ISRS concept can be extended for developing an exotic beam storage-ring to perform in-ring experiments with an interna l target [4]. In this contribution we will review the physics opportunitie s and technical challenges of the ISRS spectrometer.\n\nReferences \n\n[1] I.

For the production of primary top quarks\, it has been shown that a class of event shapes related to th e invariant mass of the hemisphere can be used to measure the top quark ma ss with a precision smaller than $\\Lambda_{QCD}$ . The maximal sensitivit y to the top mass — which plays a central role in testing the validity o f the Standard Model— is attained in the peak of the distribution\, wher e both Boosted Heavy Quark Effective Theory (bHQET)\, and Soft Collinear E ffective Theory (SCET) are applicable.\n\nThe use of Effective Field Theor ies (EFTs) allows for the factorization of expressions for various observa bles\, effectively separating contributions from different physical scales . In these factorized expressions\, the jet function —previously known a t two loops— emerges as a universal ingredient\, common to many observab les. Thus\, computing the jet function at higher perturbative orders is wa rranted. However\, studying processes at more than one loop requires dedic ated techniques to handle the large number of Feynman diagrams that contri bute. In this talk we will present our analytic computation of the three-l oop jet function for boosted heavy quarks.\n\nWe will briefly discuss the main properties and renormalization of the jet function and outline the wo rkflow for a fixed-order calculation\, including the strategies used for e valuating the master integrals. The three-loop piece of the jet function i n dimensional regularization will be presented\, and several important tes ts of our results will be discussed. Our computation provides the last mis sing piece to obtain the N$^3$LL′ resummed (self-normalized) thrust dist ribution used for the calibration of the top quark mass parameter in parto n-shower Monte Carlo generators. Additionally\, it contributes to the N$^3 $LL′-accurate invariant mass distribution of reconstructed top quarks\, which can be employed for a precise top mass determination at future lepto n colliders.\n\nhttps://indico.ific.uv.es/event/7664/contributions/25291/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25291/ END:VEVENT BEGIN:VEVENT SUMMARY:Constrained pion-pion dispersive amplitude analysis up to 1.6 GeV and resonance determination DTSTART;VALUE=DATE-TIME:20241120T100000Z DTEND;VALUE=DATE-TIME:20241120T101500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25274@indico.ific.uv.es DESCRIPTION:Speakers: Pablo Rabán Mondéjar (Departamento de Física Teó rica de la Universidad Complutense de Madrid)\nA precise description of pi on-pion interactions at low energies is\nfundamental for many processes in hadronic physics.

The standard off-shell approach to matching requires the use of a Green's basis that includes redundant and evanescent operato rs. The reduction of such a basis to a physical one is often highly non-tr ivial\, difficult to automate and error prone. However\, on-shell matching allows to perform the matching directly to the physical basis\, thus over coming the necessity to deal with redundancies and evanescent operators. \ n\nOur proposal is based on a numerical solution of the corresponding on-s hell matching equations\, which automatically implements in a trivial way the delicate cancellation of non-local terms between the full theory and t he effective one. The use of rational on-shell kinematics ensures an exact analytic solution despite the numerical procedure. In contrast to the tra ditional off-shell matching\, where one has to match only one-light-partic le irreducible Green functions\, with this approach the full amplitude is needed. In this way we only need a physical basis to perform the matching. We present the algorithm and some further applications in which the on-sh ell matching approach can be very useful\, such as the automation of the G reen’s basis reduction to a physical one\, the obtaining of evanescent c ontributions or the computation of renormalization group equations.\n\nhtt ps://indico.ific.uv.es/event/7664/contributions/25288/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25288/ END:VEVENT BEGIN:VEVENT SUMMARY:PNG-UNITsims: Halo clustering response to primordial non-Gaussiani ties as a function of mass DTSTART;VALUE=DATE-TIME:20241120T093000Z DTEND;VALUE=DATE-TIME:20241120T094500Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25295@indico.ific.uv.es DESCRIPTION:Speakers: Adrián Gutiérrez Adame (UAM - IFT)\nIn this presen tation I will talk about the PNG-UNITsims suite\, which includes the la rgest full N-body simulation to date with local primordial non-Gaussianiti es (local PNG)\, the PNG-UNIT.

We point out that logarithmi cally enhanced contributions generated from Barr-Zee diagrams with a fermi on loop are present in the aligned 2HDM\, an effect encoded in the decoupl ing limit by effective operators of dimension-6\, through the mixing of fo ur-fermion into dipole operators. The same large logarithms are absent in alternative 2HDMs where a Z2 symmetry is enforced\, which thus controls th e basis of effective operators relevant for calculating new physics contri butions to EDMs. In the aligned 2HDM these contributions are proportional to sources of CP violation that are potentially large\, which are absent i n presence of the Z2 symmetry.

This work presents an improved approach for extracting $\\alph a_s$ comparing the numerical results of lattice QCD simulations to the pe rturbative expansion of the QCD static energy. We apply R-improvement to i ts 3-loop fixed-order prediction\, enabling the subtraction of the u=1/2 r enormalon and the corresponding summation of large logarithms. We also per form resummation of large ultra-soft logs to $\\text{N}^3\\text{LL}$ accur acy using renormalization group equations. A new and more flexible paramet risation of the renormalization scale has been implemented\, allowing us t o extend perturbation theory to distances of the order of 1 fm. Perturbati ve uncertities are estimated randomly varying the parameters that specify the renormalisation scale. We have designed a highly optimised algorithm t o evolve $\\alpha_s$ based on the perturbative definition of $\\Lambda_{\\ text{QCD}}$\, which makes scanning over the strong coupling when minimisin g the $\\chi^2$ function very efficient. We also combine Lattice data from different simulations into a single dataset\, simplifying the fitting pro cedure.

These phase transitions i nduce non-analytic behavior in observables like angular momentum\, moment of inertia\, mass\, and radii\, with the intensity of this behavior direct ly tied to the latent heat of the transition. Notably\, the Seidov limit s ets a bound on the maximum latent heat a phase transition can produce befo re its excess energy density\, not compensated by additional pressure\, re sults in gravitational collapse.\n\nAdditionally\, we investigate how modi fied gravity theories\, such as quadratic f(R) gravity\, affect these phen omena. In this context\, we find that the Seidov limit undergoes substanti al modification compared to General Relativity. Breaching the Seidov limit would lead to two significant discoveries: evidence of a first-order phas e transition in neutron star matter and a deviation from General Relativit y.\n\nBased on Annals Phys. 459 (2023) 169487\, 2307.15366 and arXiv:2409. 16201 [gr-qc].\n\nhttps://indico.ific.uv.es/event/7664/contributions/25296 / LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25296/ END:VEVENT BEGIN:VEVENT SUMMARY:J/ψ leptoproduction at small transverse momentum DTSTART;VALUE=DATE-TIME:20241119T154500Z DTEND;VALUE=DATE-TIME:20241119T160000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25297@indico.ific.uv.es DESCRIPTION:Speakers: Samuel F.

To this end\, a major challenge lies in achieving greater preci sion in SMEFT calculations\, which includes the computation of observables to O(1/Λ²) (dimension-six) at one-loop and to O(1/Λ⁴) (dimension-eig ht) at tree level. Furthermore\, for consistency as well as for testing th e SMEFT against data obtained at very different scales\, the dimension-eig ht SMEFT should be renormalized to the one-loop level. This work contribut es to this endeavour by computing two-fermion renormalization group equati ons (RGEs) induced by pairs of dimension-six terms. Our approach relies on off-shell diagrammatic techniques\, for which we build a new basis of dim ension-eight Green’s functions with two-fermions and two or more Higgs f ields. We apply diagrammatic on-shell matching to minimize redundant inter actions\, relying on the equivalence of the S-matrices computed within the redundant and non-redundant Lagrangians.\n\nhttps://indico.ific.uv.es/eve nt/7664/contributions/25286/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25286/ END:VEVENT BEGIN:VEVENT SUMMARY:Vacuum amplitudes in the loop-tree duality for theoretical predict ions at colliders DTSTART;VALUE=DATE-TIME:20241119T161500Z DTEND;VALUE=DATE-TIME:20241119T163000Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25279@indico.ific.uv.es DESCRIPTION:Speakers: David Renteria-Estrada (IFIC-CSIC\, Universitat de V alència)\nThis talk presents recent advances in the cancellation of ultra violet (UV) and infrared (IR) singularities within perturbative quantum fi eld theory (QFT)\, focusing on automating theoretical tools for more preci se predictions at high-energy colliders.

This scalar decay term arises spontaneously upon chiral symmetry breaking\, despite Quantum Chrom odynamics being mediated by spin-one gluons and displaying chiral symmetry in its Lagrangian. We explore this by employing the non-perturbative quar k-gluon vertex in the Landau gauge\, alongside a constant chromoelectric f ield background similar to the Schwinger pair production in Quantum Electr odynamics. Our results support the $^3P_0$ mechanism at momenta below the fermion mass scale\, though ultrarelativistic fermions mostly exhibit $^3S _1$ quantum numbers.

Escalante-Castro (IFIC-CSIC)\nCompton gamma cam eras have been developed in recent years to image radionuclides across var ious nuclear application fields. A crucial aspect of nuclear medicine is t he precise localization of radioisotopes to guide interventional procedure s. In this context\, Compton gamma cameras offer higher sensitivity than c onventional pinhole gamma cameras\, as they do not require mechanical coll imation. Instead\, the reconstruction of the initial gamma-ray trajectory relies only on the deposited energy and the impact positions of Compton-sc attered events. Consequently\, accurately determining the position of even ts within the scintillation crystal is one of the most critical factors in fluencing image quality. An experimental study is therefore presented\, ev aluating the performance of various scintillator crystals\, differing in t hickness\, material\, covering\, and structure.\n\nhttps://indico.ific.uv. es/event/7664/contributions/25511/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25511/ END:VEVENT BEGIN:VEVENT SUMMARY:Production of pre-clinical activities of 11C for PET imaging using a HRR laser-driven proton source DTSTART;VALUE=DATE-TIME:20241119T164200Z DTEND;VALUE=DATE-TIME:20241119T165200Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25512@indico.ific.uv.es DESCRIPTION:Speakers: Aarón Alejo (IGFAE\, Universidade de Santiago de Co mpostela)\nIn recent years\, there has been a growing interest in laser-dr iven ion accelerators as a potential alternative to conventional accelerat ors [1]. A particularly promising application is the production of radionu clides relevant for medical diagnosis\, such as 11C for PET imaging. Typic ally\, the production of these nuclides is centralised at cyclotrons\, red ucing the number of facilities required\, but limiting the range of usable radionuclides to those with longer lifetimes [2]. In this context\, compa ct laser-driven accelerators appear as an appealing option for the in-situ generation of short-lived isotopes. Albeit the activities required for PE T imaging (>MBq) are well above those achievable from a single laser irrad iation (~kBq)\, the advent of high-power\, high-repetition-rate laser syst ems opens the path to demonstrating relevant activities through the contin uous irradiation\, provided a suitable target system is developed. A targe t assembly based on a rotating wheel and automatic alignment procedure for laser-driven proton acceleration at multi-Hertz rates has been developed and commissioned [3]. The assembly\, capable of hosting >5000 targets and ensuring continuous replenishment of the target with micron-level precisio n\, has been demonstrated to achieve stable and continuous MeV proton acce leration at rates of up to 10 Hz using our in-house 45 TW laser system [3] .\n\nThe continuous production of 11C via the proton-boron reaction [11B(p \,n)11C] has been recently demonstrated from our target assembly using the 1 Hz\, 1 PW VEGA-3 system (CLPU\, Spain) [4]. In an initial campaign\, an activity of ~12 kBq/shot was measured\, with a peak activity of 234 kBq a chieved through accumulation of 20 consecutive shots [4]. Furthermore\, re sults of a more recent campaign will be presented\, where activation level s in excess of 4 MBq where achieved\, as measured through using coincidenc e detectors\, and supported by online measurements of high-flux neutron ge neration. We demonstrate that the degradation of the laser-driven ion beam due to heating of optics is currently the only bottleneck preventing the production of pre-clinical (~10 MBq) PET activities with current laser sys tems. The scalability to next-generation laser systems will be explored to study the potential for production of clinical (~200 MBq) activities.\n\n **References**\n[1] A. Macchi et al.\, Rev. Mod.

However\, further advantages could be obtained if a quasi-real-time monitoring system for i on-range verification would be available. In particular\, this would help to reduce safety margins and enhance its potential benefits\, due to vario us sources of systematic uncertainty. Two of the most promising methodolog ies for in-room real-time monitoring are positron emission tomography (PET ) and prompt-gamma imaging (PGI). The PGI technique is well suited for rea l-time monitoring because of the prompt nature of the emitted radiation [L er22]\, whereas PET imaging can provide tomographic and functional informa tion relevant for studying physiological processes and tumor response.\n\n In 2016\, the concept of PGI-PET hybrid imaging system was discussed by Pa rodi as an alternative to overcome some of the limitations for each techni que [Par16]. As suggested in Ref. [Lang14]\, this concept could be impleme nted by adapting systems based on multiple Compton cameras. Hybrid PGI-PET systems are expected to open new perspectives for in-vivo real-time range monitoring [Par16]. This expectation is based on the complementarity of t he two techniques: prompt-gamma emission is more suitable for real-time mo nitoring\, while PET imaging can provide tomographic and functional inform ation valuable for monitoring physiological processes and tumor response.\ n\nWe have implemented for the first time in hadron therapy a hybrid imagi ng system based on the combination of both PGI and PET within the same set up [Bal22]\, thereby exploring the advantages of both techniques.

This therapy exploits the large neutron capture cross-s ection of boron to deliver a targeted dose from neutron irradiation. BNCT has shown great promise with the advent of accelerator-based technologies\ , which facilitate high-quality neutron beams in clinical environments [Hi r21\, Tor21]. \n\nOne of the primary challenges in current BNCT is the acc urate determination of the dose delivered to the patient. The state-of-the -art method involves measuring the boron concentration in the patient usin g PET with a 18F-labeled boron compound\, followed by determining the boro n concentration in blood during the neutron irradiation to estimate the bo ron dose. Since neutron captures in boron produce 478 keV gamma rays in 94 % of reactions\, this radiation could be potentially used for real-time do se monitoring using various imaging techniques. To date\, SPECT and Compto n imaging have been explored\; however\, the main challenges remain in ach ieving the spatial resolution required\, true online capabilities and deal ing with the harsh radiation backgrounds induced by the neutron beam durin g treatment.\n\nThe i-TED Compton Camera array\, originally designed for n uclear physics measurements of astrophysics interest\, recently has expand ed its application into medical physics through ion-range monitoring in ha drontherapy [Ler22\,Bal22]\, and is venturing further in this field aiming now at BNCT. Its large efficiency design and low neutron sensitivity make i-TED especially well suited for this task.\n\nThis contribution will pre sent additional adaptations of the original i-TED imager\, to optimize its performance for the BNCT dosimetry application. In this context\, an eval uation of the detector thicknesses has been performed to optimize it for t he 478 keV gamma rays characteristic of BNCT. Additionally\, since BNCT re quires imaging of large areas (e.g. the human head or torso) we have integ rated LM-MLEM algorithms into our imaging suite to enable 3D image reconst ruction and tomographic capabilities [Tor24].\n\nMoreover\, we have condu cted an initial experimental campaign with one iTED module at the high-flu x nuclear reactor of the Institut Laue-Langevin (ILL\, Grenoble\, France) as proof-of-concept of the imaging of 478 keV gamma rays [Ler24]. A second campaign was performed with the complete i-TED array of four Compton imag ers under more realistic conditions\, using HDPE and water phantoms surrou nding borated water disks in concentrations comparable to actual BNCT trea tments [Tor24]. \n\nI will provide an overview of the main adaptations of i-TED for BNCT\, our latest developments in 3D image reconstruction\, the results of the first proof-of-concept experiment with one i-TED module\, a nd the status of the analysis of the recently performed experiment using t he full i-TED array in more realistic conditions. \n\nReferences\n[Hir21] K.

We performed a survival and viability assay with an X-ray beam at FLASH and c onventional dose rates\, using healthy lung fibroblasts and lung cancer ce ll lines to study potential biological mechanisms that could be at the roo t of the observed differential FLASH effect.\n\n**Materials and methods**\ nHealthy lung fibroblasts (CCD19) and lung adenocarcinoma cells (A549) wer e cultured in regular DMEM supplemented with 10% FBS and penicillin/strept omycin under standard culturing conditions. Two different seeding conditio ns were irradiated. On one hand\, 24h before the irradiation the A549 cell line was seeded in MW96 plates. On the other hand\, 1·10^6 tumor cells a nd 4.5·10^5 healthy cells were collected and pellet in eppendorfs vials.\ nBoth seeding conditions were irradiated with 0-30 Gy using a modified X-r ay tube at FLASH (150 kVp and 500 mA) dose rates (34 Gy/s-88 Gy/s) and con ventional (150 kVp and 10 mA) dose rates (0.68 Gy/s-1.72 Gy/s). Doses and dose rates were determined via radiochromic films (RCF) dosimetry.\nIn vit ro clonogenic study was performed on A549 and CCD19 cells by seeding incre asing concentrations with the dose of irradiated cells in MW6 plates. Ten days later\, cells were fixed\, stained with crystal violet and number of colonies quantified with a self-developed Matlab script\, while the viabil ity assay done with the healthy cells was manually quantified. Both data w ere analyzed with the linear quadratic model. \n\n**Results**\nDosimetric equivalence FLASH vs. CONV was confirmed as long as the delivered charge r emained constant. Preliminary analysis of the results (still ongoing) sugg ests no differential biological effects related to the dose rate that is s tatistically significant. Clonogenic assays for the A549 cells showed no d ifferential dose-rate effect in the biological response\, as well as the v iability assays conducted with the CCD19 cell line.\n\n**Discussion and co nclusions**\nOn one hand\, via radiochromic film dosimetry we were able to determine the dose rates used in the experiment and the exact dose irradi ated in each shot to each eppendorf vial or MW96 plate well.\nOn the other hand\, equivalent biological results were obtained in an in vitro study a t normoxic conditions between X-ray irradiations at conventional and FLASH dose rates for both healthy fibroblasts and lung cancer cells.\n\nhttps:/ /indico.ific.uv.es/event/7664/contributions/25518/ LOCATION: URL:https://indico.ific.uv.es/event/7664/contributions/25518/ END:VEVENT BEGIN:VEVENT SUMMARY:Performance tests of the IEM-CSIC proton scanner prototype DTSTART;VALUE=DATE-TIME:20241119T155400Z DTEND;VALUE=DATE-TIME:20241119T160400Z DTSTAMP;VALUE=DATE-TIME:20260421T034818Z UID:indico-contribution-7664-25519@indico.ific.uv.es DESCRIPTION:Speakers: Amanda Nathali Nerio Aguirre (IEM-CSIC)\nProton ther apy requires precise knowledge of the patient anatomy to ensure an accurat e dose delivery [1]. X-ray computed tomography (CT) images are used nowada ys to calculate the relative stopping power (RSP) needed for proton therap y treatment planning [2]. Recent studies indicate that tomographic imaging using protons has the potential to provide a more accurate and direct mea surement of RSP with a significantly lower radiation dose than X-rays [3]. A proton CT (pCT) scanner prototype is under development at the IEM-CSIC. It comprises a tracking system of two double-sided silicon strip detector s and the CEPA4 detector as the residual energy detector. This pCT scanner prototype was tested at the Cyclotron Centre Bronowice (CCB) facility in Krakow\, Poland\, during three experimental campaigns in 2021 and 2022. Se veral samples were used to test the spatial resolution and RSP determinati on capabilities of the scanner in radiography and tomography imaging modes . Volumetric phantoms composed of matrices made of PMMA with inserts of ai r\, ethanol\, water\, Delrin\, Teflon\, and aluminum were imaged. The radi ographs displayed great fidelity to the shapes of the studied samples. Th e spatial resolution of this proton imaging scanner prototype is better th an 2 mm and the MTF-10%=0.3 line pairs per mm in radiography mode [4]. The RSP resolution of the scanner has also been studied and the resulting RSP values are in good agreement with previously reported data [5]. We are cu rrently engaged in the data analysis of new samples for the study of radio graphs and tomography scans using proton beams with energies up to 200 MeV .\nAt this conference\, we will present preliminary findings\, including t he imaging capabilities of our prototype\, showcasing its potential applic ations for the future of medical imaging detectors.\n\nReferences\n[1] C.

In the mass region around A=100\, there exist clear cut examples of the rapid appearance of deformation such as Zr (even-even) [2] and Nb isotopes (odd-even) [3]\, which can be understood in terms of the coexistence of two different configurations\, i.e.\, shape coexistenc e. Sr [4] isotopes are also good candidates to study the onset of nuclear deformation and the influence of shape coexistence\, while Ru and Mo [5] isotopes seem to be placed at the border of dilution of shape coexistence In addition\, the structural evolution of odd-mass isotopes in this regio n is significant due to the diversity of configurations and coexisting sha pes and to the enhancement of the onset of deformation [3].\nIn this contr ibution will be used as framework the Interacting Boson-Fermion Model [6] with Configuration Mixing (IBFM-CM) to introduce a mean-field view (intri nsic state) for studying the evolution of the nuclear deformation in A=100 region\, focussing on the case of odd-even Nb isotopes. Two complementary approaches will be used for studying shape evolution: first\, an algebrai c approach employing a laboratory frame of reference\, and secondly\, a ge ometric-oriented method within the context of an intrinsic state formalism . The objective is to compare the onset of deformation in Nb isotopes with the even-even cases\, such as Sr and Zr\, extracting information from the intrinsic state\, but also from spectroscopic properties.\nTo conclude\, by applying the IBFM-CM framework and employing both algebraic and geometr ic approaches\, this contribution aims at providing insights into the evol ution of nuclear shapes in even-even and odd-even nuclei in the mass regio n around A=100.\n\n[1] K.
