【摘要】 本课题利用硅光电信增管（SiPM）的增益与电压成正相关特性,设计了具有温度补偿特性的SiPM探测器偏置电源,并进行了实验测试。测试结果表明:在恒温箱内不同温度下的¹³⁷Cs全能峰测量,加入温度补偿后,¹³⁷Cs全能峰的峰位道址变化从31.9%变减小为1.3%,表明SiPM的增益具有良好的温度稳定性。更多还原

【Abstract】 In this paper,a bias power supply of SiPM detector with temperature compensation is designed and tested by using the positive correlation between SiPM gain and voltage.The Experimental test results show that:in the ¹³⁷Cs all-around peak measurement at different temperatures in a thermostat,after temperature compensation is added,the peak location change of ¹³⁷Cs all-around peak decreases from31.9% to 1.3%,indicating that the gain of SiPM has good temperature stability.更多还原
