摘要:

硅光电倍增器(SiPMs)的增益随偏压的增加而增加,随温度的升高而减小。为了使SiPM以稳定的增益工作,可以重新调整偏置电压以补偿温度变化。我们已经测试了这一概念与30 SiPM从三个制造商(滨松,KETEK和CPTA)在欧洲核子研究中心的气候室中运行的$1^\circ \rm C$和$48^\circ \rm C$之间的不同温度。我们构建了一个自适应电源,它使用偏置电压对温度的线性依赖关系。我们同时稳定四个SiPM,只有一个补偿参数的四个SiPM的偏置电压的重新调整。对于所有测试的Hamamatsu和CPTA SiPM,我们实现了在$20-30^\circ C$温度范围内将增益变化限制在$\pm 0.5\%$以下的目标。

英文摘要:

The gain of silicon photomultipliers (SiPMs) increases with bias voltage and decreases with temperature. To operate SiPMs at stable gain, the bias voltage can be readjusted to compensate for temperature changes. We have tested this concept with 30 SiPMs from three manufacturers (Hamamatsu, KETEK and CPTA) operating in a climate chamber at CERN by varying temperatures between $1^\circ \rm C$ and $48^\circ \rm C$. We built an adaptive power supply that uses a linear dependence of the bias voltage on temperature. We stabilized four SiPMs simultaneously with only one compensation parameter for the readjustment of the bias voltage of four SiPMs. For all tested Hamamatsu and CPTA SiPMs we achieved our goal of limiting gain changes to less than $\pm 0.5\%$ in the $20-30^\circ C$ temperature range.
