Neutron hardness of EJ-276 scintillation material
Abstract
This paper presents the results of the fast neutron irradiation (En > 0.5 MeV) of an EJ-276 scintillator performed in the MARIA research reactor with fluence up to 5.3 × 1015 particles/cm2. In our work, four samples with size phi 25.4 mm × 5 mm were tested. The changes in the light yield, emission and absorption spectrum and neutron/gamma discrimination using PuBe source before and after irradiation are presented. The figure of merit in neutron/gamma discrimination based on the charge integration method for different neutron fluences and different short gate integration times are determined.
