Abstract

Abstract

To achieve the purpose of monitoring the fast neutron fluence rate outside the nuclear power plant, the development of a miniaturized fast neutron detector based on zinc sulfide (ZnS) scintillator was carried out. To verify the neutron radiation resistance performance of the fast neutron detector, the radiation sample design of the fast neutron detector was carried out in combination with the characteristics of the irradiation device and the requirements of the irradiation components, and the Monte Carlo software and COMSOL Multiphysics 5.5 simulate and analyze the particle transport and overall temperature field distribution in a fast neutron detector based on zinc sulfide (ZnS) scintillator. The irradiation sample of the detector is designed iteratively, and the irradiation sample of the fast neutron detector of ZnS scintillator is designed. At the same time, based on the in-depth analysis of the simulation data, the temperature characteristics of various materials under the irradiation field are extracted, which provides theoretical guidance for the subsequent processing and manufacturing of fast neutron detector irradiation samples and the irradiation verification test of a single material.
