摘要

介绍了3He半导体夹心谱仪的探头组件和电子学系统

开展了热中子调试

获得快中子临界装置上0.1–1.3 MeV的能谱数据。测量结果与6Li夹心谱仪在0.3–1.3 MeV范围非常符合

证明该谱仪用于测量快中子临界装置泄漏谱是可行的。

Abstract

The detector design and electronics system of a 3He semiconductor sandwich spectroscopy is reported in this paper.The thermal neutron test is conducted and neutron spectra in 0.1–1.3 MeV in the critical assembly are measured.The results indicate that data of 0.3–1.3 MeV neutrons are consistent with the 6Li spectroscopy.So the feasibility to measure leakage neutron spectra in the critical assembly using the 3He spectrometer is proved.
