介绍了中子多重性测量分析方法的理论关系式以及中子脉冲序列的形成原理,并利用MC-NPX与MATLAB程序模拟便携式中子符合探测器(PNCC)进行中子多重性测量,得到了铀材料的中子多重性分布,实现了中子脉冲序列的采集.实验研究验证了便携式中子符合探测器用于中子多重性测量的可行性.

This paper mainly describes the theoretical formula and the principle of neutron pulse train generation, and then uses MCNPX and MATLAB program to simulate the Portable Neutron Coincidence Counter(PNCC) for neutron multiplicity counting. The results have got the neutron multiplicity distribution of uranium materials and acquired the neutron pulse train. This experiment has verified the feasibility that PNCC can be used in neutron multiplicity counting. © 2016, Editorial Board ...
