本文介绍了一种采用EJ-301闪烁液、R9420光电倍增器和自制前置放大器的中子探测器结构。对于能量范围为0~3000keVee的中子探测，探测器的能量线性度、效率响应和中子/伽马分辨能力都得到了保证。在中子/伽马分辨能力方面，对阈值穿越时间法(TCT)、脉冲梯度分析法(PGA)、电荷比较法(CC)和相关模式识别法(CPR)等4种脉冲形状判别法进行了评价和讨论，其中CPR方法具有最好的中子/伽马分辨能力。
This paper presents a neutron detector configuration using EJ-301 scintillation liquid, a R9420 photo-multiplier and a homemade preamplifier. The detector qualities which include the energy linearity, efficiency response and neutron/gamma discrimination are guaranteed for neutron detection in the energy range from 0 to 3000 keVee. Regarding the neutron/gamma discrimination capability, four pulse shape discrimination (PSD) methods which are the threshold crossing time (TCT), pulse gradient analysis (PGA), charge comparison (CC) and correlation pattern recognition (CPR), were evaluated and discussed; among of these, the CPR method provides the best neutron/gamma discrimination.
