摘要
在使用锗酸铋闪烁晶体γ射线探测器对γ射线能谱进行测量时,由于环境温度的变化,会引起探测器能量分辨率的变化和所测谱峰位的漂移。采用合适的方法对探测器进行冷却和保温,可以很好地解决由于温度变化给测量结果带来的误差问题。
When BGO glitter crystal γ detector is used to measure γ spectrum, the energy resolution of detector varied and the location of apex detected moved the variety of the environment temperature. It can resolve the error caused by the temperature variety very well to develop a method to cool the detector and keep its temperature.
