Abstract
Cs2LiYCl6∶Ce(CLYC)crystals have excellent linear response,high light yield and strong neutron-Gamma discrimination capability.Therefore,CLYC detectors have board development prospects in the fields of neutron physics and neutron application technology.The Prompt gamma neutron activation analysis(PGNAA)with the performance of high-precision and multi-element,which can be widely used in non-destructive testing fields such as industry,environment,and safety.In this research,the CLYC detector can be used in was tested to explore its application prospect in the field of PGNAA.The purpose of CLYC research is explore its application prospect in field of PGNAA.In addition,a gamma analysis program based on Gravel algorithm was developed,and a method of computing the number of iterations based on Mean Relative Error was proposed.They can be used in γ energy spectrum analysis.Also,experimental measurements of neutron sources(Pu-C)and gamma sources(22Na,60Co,137Cs,152Eu)were carried out.The results showed that the n-γdiscrimination ability of CLYC detector was excellent detector,which can eliminate the influence of neutrons effectively in the neutron gamma mixed field.And the program of y deconvolution still could compute accurately in the complex γ-field environment.关键词
