摘要: 硅光电倍增管(Silicon Photomultiplier, SiPM)是新一代的半导体光子探测器,被广泛应用在高能物理、核医学成像及核物理等领域。由于不同的SiPM的偏置电压不同,为满足SiPM的工作电压需求,设计一款电压可调的,且具有温度自适应功能的高压电源。高压电源主要利用DC/DC模块产生高压来给SiPM供电。高压电源电压最高可达到200 V,通过改变电位计的阻值进行分压,使DC/DC模块输出不同的电压值。最后完成了DC/DC模块的稳定性、温度自适应测试,高压电源的性能及工作特性等测试,结果表明,DC/DC模块的积分非线性为0.14‰,模块工作稳定;在不同温度下,系统增益的最大变化率为1.12%,系统增益保持相对稳定;自制的高压电源最大波动约为0.01 V,工作稳定;纹波系数在0.02%以下,具有低纹波特性。同时,在同一测试环境下,高压电源和商用电源全能峰分辨率分别为7.84%和9.88%,自制高压电源的性能要优于商用电源。Abstract: Silicon Photomultiplier (SiPM) is a new generation of semiconductor photon detector, which is widely used in high-energy physics, nuclear medical imaging and nuclear physics and other fields. As the bias voltage of different SiPM is different, a high voltage power supply with adjustable voltage and temperature adaptive function is designed to meet the working voltage demand of SiPM. High voltage power supply mainly uses DC/DC module to generate high voltage to supply power to SiPM.The voltage of the high-voltage power supply can reach up to 200 V. The DC/DC module outputs different voltage values by changing the resistance value of the potentiometer to carry out partial voltage. Finally, the stability of DC/DC module, temperature adaptive testing, the performance and working characteristics of the high-voltage power supply plate were completed. The results show that the integral nonlinearity of the DC/DC module is 0.14‰, and the module works steadily. At different temperatures, the maximum change rate of system gain is 1.12%, and the system gain remains relatively stable. The maximum fluctuation of the self-made high-voltage power supply is about 0.01 V, and the work is stable. The ripple coefficient is below 0.02%, with low ripple. Meanwhile, in the same test environment, the resolution of the all-purpose peak of the high-voltage power supply and the commercial power supply are 7.84% and 9.88% respectively, and the performance of the self-made high-voltage power supply is better than that of the commercial power supply.
