Group II-VI semiconductors are being explored for room-temperature X-ray imaging due to their excellent properties, especially high resistivity and wide bandgap. However, their performance is often limited by crystalline defects and surface imperfections that trap charges and increase leakage currents.
Wafer inspection to ensure the quality of base materials through optical means prior to...
The development of very low background γ-ray spectrometers has led to multidetector systems, such as Mazinger. Mazinger is an array of two HPGe detectors and two NaI(Tl) anti-Compton rings in anticoincidence configuration. The detector shielding combines passive shielding, composed of three layers of iron, lead and copper and active shielding, consisting of two anti-muon veto detectors in...
Boron Neutron Capture Therapy (BNCT) is an experimental form of radiotherapy that uses boron, injected to the patient within a target molecule that accumulates selectively in cancerous cells. This therapy exploits the large boron neutron capture cross-section to deliver a targeted dose from neutron irradiation. BNCT has shown great promise with the advent of accelerator-based technologies,...
Scintillator-based diagnostics, such as Fast Ion Loss Detectors (FILD) [1] and Ion-Neutral Particle Analyzers (INPA) [2], play a crucial role in characterizing energetic particle behavior in magnetic confinement fusion devices. These diagnostics rely on visible light emission induced by energetic ion irradiation (ionoluminescence). A common assumption in theses diagnostics is that light...
Compton cameras are emerging as an interesting tool in medical imaging. The IRIS group of IFIC has been working on such systems for 20 years and has developed several prototypes with different types of detectors. The group currently coordinates the European project AIDER for developing a clinical system and testing it with patients. The main results achieved in the projects MIDAS and ICOR and...
Conventional X-ray radiography is the current standard for industrial non-destructive testing of metallic parts. However, some limitations arise due to the low penetration depth of X-rays for certain materials or their thickness. This is the case for metal additive manufacturing, where quality control and internal inspection are critical in most applications. In this paper we report the use of...
Introduction:
Neutron dosimetry still faces major challenges, especially in high-energy radiation fields found in facilities like particle accelerators and hadron therapy centers, where neutrons are generated as secondary particles. The difficulty intensifies in pulsed radiation structures, typical of advanced treatments like FLASH therapy or pulsed neutron field generated by...
Over the past few years, Low-Gain Avalanche Detectors (LGADs) have demonstrated excellent timing performance, showing great potential for use in 4D tracking of high-energy charged particles. Carbon co-doping is a key factor for enhancing LGAD performance, which are detectors with intrinsic amplification, in harsh radiation environments. This work presents a broad pre-irradiation...
External trigger systems are essential in ion beam facilities because they enable precise synchronization and detection with other experimental or diagnostic equipment. This synchronization is crucial for achieving reproducible measurements and improving the temporal resolution of some experiments [1] . In this contribution, we report on the development and commissioning of a external trigger...
Compton imaging is a promising technique for Prompt Gamma (PG) imaging in range verification during hadron therapy (HT). In neutron monitoring, however, most existing systems register only integral off-field neutron fluence values, without providing information on the spatial origin. Dual neutron–gamma imaging is also of significant interest for applications in nuclear safety and security. To...
Boron Neutron Capture Therapy (BNCT) is an experimental radiotherapy technique in which boron linked to a drug, 10B-BPA, is administered to the patient that selectively accumulates in cancer cells. This therapy relies on the large boron neutron capture cross-section to deliver a targeted dose from neutron irradiation. With the development of accelerator-based technologies, which enable the...
Las mediciones precisas de radionúclidos son cruciales en la datación absoluta en estudios paleoclimáticos. Mazinger, un espectrómetro de rayos γ de muy bajo nivel de fondo y alta eficiencia, se ha actualizado con dos detectores antimuones tipo veto y se ha reconfigurado su electrónica de adquisición, logrando mejorar los límites de detección y gestionar tasas de eventos más altas provenientes...
The $^{14}C$ dating facility at the University of Salamanca, based on the compact MICADAS (MIni CArbon DAting System) [1], has been in operation for over three years. This work presents a detailed status report on the facility's performance, sample preparation methodologies, and statistical validation of results.
A wide variety of materials have been processed, including collagen, corals,...
