Abstract

The Mu2e experiment at Fermilab will search for the coherent $\mu \rightarrow e$ conversion on aluminum atoms. The detector system consists of a straw tube tracker and a crystal calorimeter. A pre-production of 150 Silicon Photomultiplier arrays for the Mu2ecalorimeter has been procured. A detailed quality assurance has been carried out on each SiPM for the determination of its own operation voltage, gain, dark current and PDE. The measurement of the mean-time-to-failure for a small random sample of the pro-production group has been also completed as well as the determination of the dark current increase as a function of the ioninizing and non-ioninizing dose.

用于Mu2e实验的自定义SiPMs阵列的质量保证

费米实验室的Mu2e实验将寻找铝原子上的相干$\mu \rightarrow e$转换。该探测器系统由吸管跟踪器和晶体量热计组成。已经为mu2热量计采购了150个硅光电倍增管阵列的预生产。对每个SiPM进行了详细的质量保证，以确定其自身的工作电压，增益，暗电流和PDE。对促生产组的一个小随机样本的平均失效时间的测量也已完成，以及确定暗电流增加作为电离和非电离剂量的函数。
