【摘要】 为了完成中子注量率测量以及测量实验装置内部不同位置的裂变率分布(要求进行绝对测量),设计制作了小型平板裂变电离室。利用裂变电离室在特定中子场下测量注量率既方便快捷又经济实用,在裂变室的设计中主要考虑了体积小、结构材料少的特点。本文叙述了裂变室的结构和制作工艺过程,给出了性能测试结果。裂变室探测效率为91.7%。更多还原

【Abstract】 To conduct the measurement of neutron flux and the fission rate distribution at several position in assemblies,the micro plate fission chamber was designed and fabricated.Since the requirement of smaller volume and less structure material was taken into consideration,it is convinient,commercial and practical to use fission chamber to measure neutron flux in specific condition.In this paper,the structure of fission chamber and process of fabrication were introduced and performance test result was presented.The detection efficiency is 91.7%.更多还原
