中子反照效应实验理论设计

Theoretic Design of Neutron Albedo Effect Experiment

为深化中子反照效应的认识,获得宏观测量数据,本文开展了中子反照效应实验的理论设计,给出了反照效应分析的理论公式。采用两组不同的实验状态分别给出了直照能谱和反照能谱下两种核素反应率的测量结果,再通过某测点这两种核素反应率的测量实现反照影响的定量分析。分析认为,给出的理论公式和实验布局方案是有效的,获得实验测量数据后可给出中子反照效应的定量信息。

To deepen the knowledge of neutron albedo effect and get macroscopic measure data,the theoretical research of neutron albedo effect experiment was performed.The theoretical design of neutron albedo effect experiment was developed and the theoretical formula was determined.With two different experiment states,reaction rates of two nuclides under source neutron spectra and albedo neutron spectra can be measured.Then albedo effects by reaction rate of some measure points are quantified.The theoretical formula and the experiment layout scheme are effective.With experiment measure data,more quantitative informations of neutron albedo effect can be obtained.
