Calibration of EJ-276 plastic scintillator for neutron–gamma pulse shape discrimination experiments
(2021) Ryabeva, E. V.; Urupa, I. V.; Lupar, E. E.; Kadilin, V. V.; Skotnikova, A. V.; Kokorev, Y. A.; Ibragimov, R. F.; Рябева, Елена Васильевна; Урупа, Илья Викторович; Лупарь, Евгений Эдуардович; Кокорев, Яков Александрович; Ибрагимов, Ренат Фаридович
© 2021 Elsevier B.V.Calibration of the scintillator detector based on a plastic scintillator EJ-276 for neutron–gamma pulse shape discrimination (PSD) experiments was carried out. Optical characteristics of electrons as the function of their deposited energy were experimentally studied. The calibration was implemented by comparing the experimental response from gamma sources with that obtained by means of GEANT4 simulation. It is shown that a similar relationship for protons built on the basis of the published data on EJ-299-33, is also applicable to EJ-276 which confirms the information about the equivalence of these scintillators. The experimental response of the EJ-276 to 14 MeV neutrons is compared with Geant4 simulation data. The experimental and simulated data were also presented as the function of light output in electronic equivalent (MeVee) obtained by both exponential and Birks’ laws. An experimental setup was constructed with Ø51 × 51 mm EJ-276 scintillator. The CAEN DT5730B digitizer was used for PSD signal discrimination. Based on the current experiments and the earlier published data a calibration relation between the setup channels and the light output was obtained in electronic equivalent (MeVee).

EJ-276 based neutron spectrometer with neutron–gamma pulse shape discrimination capability
(2022) Gaganov, V. V.; Vershinin, I. S.; Ryabeva, E. V.; Molodtsev, D. A.; Urupa, I. V.; Ibragimov, R. F.; Lupar, E. E.; Savin, D. I.; Рябева, Елена Васильевна; Урупа, Илья Викторович; Ибрагимов, Ренат Фаридович; Лупарь, Евгений Эдуардович
© 2022 Elsevier B.V.This article demonstrates the performance of the EJ-276 plastic scintillator-based neutron radiation spectrometer with neutron–gamma separation capability. This work continues the earlier research devoted to the demonstration of the EJ-276 spectrometric capabilities. An NG-150M generator located at RFNC-VNIIEF (Sarov) was used as a neutron source. Neutron energy distribution was unfolded for several angles between neutron generator and the target-scintillator direction using a Geant4 simulated response matrix and a set of experimental response spectra. The experimental neutron spectra are compared with the calculated ones. DT neutron unfolded energy uncertainty is 2%. The accompanying gamma radiation spectra were unfolded with the same uncertainty.

Ensuring safe operation of university neutron generators Обеспечение безопаснои работы генераторов неитронного излучения в вузе

© 2020 Obninsk Institute for Nuclear Power Engineering, National Research Nuclear University 'MEPhI'. All rights reserved.A package of organizational and engineering arrangements has been considered to ensure safe operation of portable neutron generators in a university environment. The dose rate from the fast neutron generator's neutron radiation in rooms permanently or temporarily occupied by personnel or the public was mathematically simulated using the GEANT4 code. Dedicated biological shielding has been developed and built, and measures have been put in place for the radiation dose monitoring using state of the art health physics equipment and for remote control of the fast neutron generator's neutron yield, as well as to limit the neutron yield and the neutron generator operating time, to prevent access into rooms with operating generators, and to monitor the radiation dose values using special purpose devices (dosimeters, radiometers, etc.). It has been shown that the biological shielding built and the fast neutron generator's yield of up to 5.106 n/s provide for the equivalent dose rate in permanently occupied rooms not exceeding 0.3 μ Sv/h, which is an order of magnitude as low as the university dose rate limit of 3 μSv/h.

Method of the known cross sections for calibration of the fast neutron spectrometer with a single-crystal stilbene based detector

The present work is devoted to implementation of the stilbene-based neutron spectrometer energy calibration method. The results of experiments with portable neutron generators and 238PuBe source and scattering materials with known cross sections are used for this method. It is shown that the submitted method makes it possible to carry out fast neutron spectrometry in the energy range from 1 to 15 MeV with the uncertainty of the unfolded neutron energy no more than 200 keV. Neutron spectra unfolding was carried out based on the measured spectra and a Geant4 simulated response matrix. Unfolded spectra were compared with the literature data and reference spectra.
