Abstract

Abstract

In fast neutron radiography, scintillator plates are often employed as converters of fast neutron radiation. In this paper, the simulation of interaction between BC400 scintillator plates and vertical-incidence D-T neutrons is presented, and the point spread function of scintillator plates is calculated, which exhibits a stable profile during the thickness increasing of plates from 2 mm to 100 mm. The calculation also indicates that, for a certain spatial resolution, there is not an improvement in the contrast of neutron images when the thickness of plates increases.
