Abstract A novel neutron compact spectrometer with an isotropic response called Neutron Capture Therapy Activation Compact Spectrometer is presented (**). The device sensitive from thermal up to 100 keV neutrons, and it designed for working in a single irradiation exposure. detector geometry composed by spherical moderator shell containing different material foils exhibiting radiative capture resonances covering the epithermal energy domain. simulation results on optimization elements choice...
Abstract A directional neutron spectrometer named NCT-WES (Neutron Capture Therapy Wide Energy Spectrometer) was developed for quality assurance of the therapeutic beam in Neutron (NCT). operates as a “parallelized” Bonner spheres spectrometer, embedding six semiconductor-based thermal detectors collimated cylindrical moderator. With objective validating simulation model used to derive its response matrix, irradiations reference monoenergetic fields were performed at National Physical...
Abstract Characterising neutron sources for calibration or generic testing purposes is a complex task, as the spectrum may depend, to some extent, on construction characteristics of source. Bonner spheres (BS) are traditional spectrometric transfer instruments, but they very sensitive room scatter and required measurements highly time consuming. The recently developed NCT-WES device, belonging family Single Moderator Neutron Spectrometers, has been proposed convenient alternative BS. This...
The ANET project aims at developing 2D compact neutron collimators for imaging applications. results of the collimator performances, presented in this communication, are based on data collected FISH beamline TU-Delft. Two independent methods to evaluate radiography resolution described and discussed, as well a comparison beam divergence with or without collimator.
Abstract Within the INFN-based project SAMADHA, environment neutron spectrum measurements were performed at 3480 m a.s.l. on Italian western Alps. An extended range Bonner Sphere Spectrometer was used, that especially designed to operate unattended and discriminate genuine events from spurious ones. In addition of fluence rate, its energy distribution related ambient dose equivalent, as well arrival time also studied. The high-energy component rate compared literature data measured with same...
In this work the concept of a novel slow neutron collimator and way to operate it are presented. The idea is based on possibility decouple device field-of-view from its collimation power. A multi-channel geometry proposed consisting chess-board structure where highly neutron-absorbing channels alternated air channels. borated polymer was purposely developed produce attenuating components in form square-sectioned long rods. scalable multiple sectors can be arranged. geometrical parameter LD,...
This paper presents the first determination of spatial resolution ANET Compact Neutron Collimator, obtained with a measuring campaign at LENA Mark-II TRIGA reactor in Pavia. novel collimator consists sequence collimating and absorbing channels organised chessboard-like geometry. It has scalable structure both length field view. is characterized by an elevated collimation power within limited length. Its scalability compactness are added values respect to traditional system. The prototype...
Abstract A new directional neutron spectrometer called NCT-WES (Neutron Capture Therapy Wide Energy Spectrometer) was recently developed within the INFN ENTER_BNCT project. This device constitutes a more compact and portable alternative to state-of-the-art spectrometers. The used for first time characterise near-target field produced by an accelerator-driven D–D fusion source. operates as “parallelised” Bonner spheres spectrometer, embedding six semiconductor-based thermal detectors in...
Abstract Boron Neutron Capture Therapy (BNCT) is a therapeutic treatment for malignant tumors that utilizes the nuclear reactions happen when thermal neutrons are captured by boron-10 atoms to selectively destroy designated cells. Boron-10 biochemically accumulated inside tumor target, which then irradiated with neutrons. In recent years, possibility obtain accelerator based intense neutron beams has given boost diffusion of BNCT also in Europe, removing need reactors. this contest,...

The e_LiBANS project aims at creating accelerator based compact neutron facilities for diverse interdisciplinary applications. After the successful setting up and characterization of a thermal source on medical electron LINAC, similar assembly epithermal neutrons has been developed. is an Elekta 18 MV LINAC coupled with photoconverter-moderator system which deploys ({\gamma},n) photonuclear reaction to convert bremsstrahlung photon beam into field. This communication describes development...
