摘　　要：论文旨在实测评比用于中子探测的EJ254塑料闪烁体、EJ339液体闪烁体和EJ276塑料闪烁体的n-γ甄别性能,因此搭建了以有机闪烁体、光电倍增管、数字化系统为组合的实验装置,利用脉冲形状甄别方法中的电荷比较法对三种闪烁体的n-γ甄别性能进行了实验测量。最终得到EJ339液体闪烁体的n-γ甄别性能最好的结论。This article aims to measure and compare the n-γdiscrimination performance of EJ254 plastic scintillator,EJ339 liquid scintillator and EJ276 plastic scintillator for neutron detection.Therefore,a combination of organic scintillator,photomultipli⁃er tube,and digital system is built.Using the charge comparison method in the pulse shape discrimination method,the n-γdiscrimi⁃nation performance of the three scintillators is measured experimentally.Finally,it is concluded that the n-γdiscrimination perfor⁃mance of the EJ339 liquid scintillator is the best.
