DESCRIPTION:Speakers: Benedetta Brusasco (UPC - Universitat Politècnica d
 e Catalunya)\n**Introduction:**\nNeutron dosimetry still faces major chall
 enges\, especially in high-energy radiation fields found in facilities lik
 e particle accelerators and hadron therapy centers\, where neutrons are ge
 nerated as secondary particles. The difficulty intensifies in pulsed radia
 tion structures\, typical of advanced treatments like FLASH therapy or pul
 sed neutron field generated by Synchro-Cyclotron machine. Another critical
  issue is the limited portability of many active neutron dosimetry devices
  currently used in radioactive environments. To overcome these shortcoming
 s\, the Spanish initiative\, the LINrem Project\, aims to develop innovati
 ve solutions for neutron area dosimetry and spectrometry\, addressing the 
 key limitations that currently affect this field.\n\n**Materials and metho
 ds:**\nThe **LINrem Project** consists of two patented active dosimeters: 
 the LINrem\, with sensitivity up to 10 MeV\, and LINremext dosimeter\, des
 igned for an extended range [1\,2\,3].  Their innovative design enables th
 eir use in very high dose environments\, in both continuous and pulsed rad
 iation fields.\nThe **LINpass** is the LINrem passive version based on the
  ThermoLuminiscent Detectors (TLD) enriched with Li6 and 7. The LINpass ca
 n provide solutions for areas where ionizing radiation is too high and act
 ive instruments saturate\, such as in pulsed beam/FLASH therapy. Furthermo
 re\, it can be used for radiation protection purposes. \nIn the LINrem fam
 ily there is also present a neutron spectrometer called **NESTA**: a Neste
 d Neutron Spectrometry Array. It is composed of 16 matrixes with a respose
  from thermal neutron until 10GeV. The innovative concept involves differe
 nt blocks that nest one inside the other\, making the device easy to trans
 port. All these instruments were tested in presence of high-energy neutron
  reference fields (CERF at CERN). As regards the LINrem active ambient neu
 tron dosimeters were employed to measure secondary neutrons generated in h
 adron therapy facilities under near-clinical conditions\, IBA Proteus Plus
  and IBA Proteus One.\n\n**Results and Conclusions:**\nThe LINrem dosimete
 rs showed reliable performance in validation tests at reference facilities
  (within 10% deviation) and excellent agreement with commercial devices\, 
 such as WENDI-II\, in hadron therapy environments. We present a summary of
  the project milestones\, showcasing the key findings from validation and 
 intercomparison exercises conducted under challenging conditions (fast\, h
 igh-energy and pulsed neutrons).\n\n**References:**\n[1] Ariel Tarifeño-S
