摘要
通过开展溴化镧探测器温度实验,研究了温度变化对溴化镧探测器性能的影响。研究表明,在-10℃50℃范围内,溴化镧探测器的能量分辨率变化不超过±5%,峰总比变化不超过±6%,不会影响探测器的使用。但是道址随温度变化明显,需要在环境温度变化时做好稳谱。
We report on the research of temperature influence on the performance of LaBr3 detector. The result of temperature experiments show that energy resolution of LaBr3 detector changed within ± 5 % and peak - to - total ratio of LaBr3 detector changed within ± 6% from - 10℃ to 50℃, and the temperature changes during the experiment had no effect on the use of LaBr3 detector. The channel of peak position changed obviously, thereby spectrum stabilization had to be done with the change of ambient temperature.
