论文摘要
在这项工作中,我们将记录基于SIPM的光电探测器的设计和性能,其表面积为100 cm $^2 $,以替代PMTS。将94个sipms的信号求和,以产生一个聚合的输出,该输出在液氮中表现出比整个表面低于100 cps的深色计数速率(DCR),信号与噪声比高于13,而定时分辨率优于5.5 ns。该模块在5 V时以大约360兆瓦的速度进食,在100 $ω$差异线上的动态范围超过500个照片电子。该装置与室温下的操作兼容,DCR增加了约6个数量级。
In this work we will document the design and the performances of a SiPM-based photodetector with a surface area of 100 cm$^2$ conceived to operate as a replacement for PMTs. The signals from 94 SiPMs are summed up to produce an aggregated output that exhibits in liquid nitrogen a dark count rate (DCR) lower than 100 cps over the entire surface, a signal to noise ratio better than 13, and a timing resolution better than 5.5 ns. The module feeds about 360 mW at 5 V with a dynamic range in excess of 500 photo-electrons on a 100 $Ω$ differential line. The unit is compatible with operations at room temperature, with a DCR increased by about 6 orders of magnitude.
