Study on temperature characteristics of LaBr₃ detector

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. (authors)
