摘要

采用大体积的正比计数探测器和能谱分析方法对37Ar的测量效率进行了研究。主要分析了影响正比计数管效率的阈修正、端效应和壁效应三大因素。结果表明

阈修正系数与峰面积的计算方法有关。当计数管压力大于200kPa时

计数管的壁效应修正小于1%

可以忽略。最后给出了计数管的效率的计算公式。

Abstract

37Ar detection efficiency for large volume gas proportional counter by using the spectrum analysis method was studied. The paper focused on factors affecting mostly efficiency of the counter

i.e. threshold correction

end-effect and wall-effect. The results show that the threshold correction coefficient is relative to method of peak calculation for 37Ar and wall-effect coefficient is less than 1% and can be ignored when counter’s pressure is larger than 200kPa. At last the formula of efficiency for counter is given.
