Design and Analysis of Silicon Photomultiplier Bias Compensation Power Supply
Silicon Photomultiplier Tube is an advanced solid-state photon detection technology,which inherits the high performance characteristics of traditional photomultiplier tube(PMT)and integrates a large number of SPAD arrays working in Geiger mode with its unique architecture,which has obvious advantages.The breakdown voltage of Silicon Photomultiplier(SiPM)will drift with the change of temperature,which will affect the stability of internal gain and adversely affect key performance indexes such as image reconstruction accuracy and energy resolution.Based on this,this paper develops a dynamic compensation circuit that can adapt to the change of environmental temperature in real time,realizes the precise regulation of the bias voltage of SiPM,effectively suppresses the gain drift effect caused by temperature,and makes SiPM devices keep the bias voltage stable under different temperature conditions.
