摘要 中国实验快堆燃料破损覆盖气体监测系统γ谱仪采用的是ORTEC公司的HPGe γ谱仪,监测对象是覆盖气体(氩气)。由于很难找到谱仪效率刻度相对应的标准气体体源,对谱仪的效率刻度带来了困难。本文在参考大量文献的基础上利用点源模拟的方法来进行HPGe γ谱仪的全能峰效率刻度,解决了中国实验快堆燃料破损覆盖气体监测系统(C31系统)谱仪效率刻度的困难。 The cover gas monitoring system(C31) of China Experimental Fast Reactor(CEFR) use the ORTEC company's HPGe gamma-ray spectrometer to monitor the radioactive fission gas.It's hard to find a standard volume source to calibrate the peak efficiency for this HPGe detector.This paper uses the calibration method of the peak efficiency by means of point source simulation for this HPGe gamma ray spectrometry.In this way we find a solution to calibrate the peak efficiency for the C31's gamma-ray spectrometer.
