The DarkSide program aims to a WIMP direct detection using a dual phase argon time projection chamber. The next generation experiment, DS-20k, will be a detector in excess of 20 tonnes of fiducial mass. A pivotal aspect to the sensitivity of the experiment is its light detection technology. The DarkSide collaboration decided to adopt Silicon Photomultipliers for its Photo Detector Module (PDM). Each PDM includes a total active surface of 25 cm 2 of SiPMs read-out by a front-end board capable of aggregating all the signals in a single analog output with a signal-to-noise ratio larger than 8. In this talk an overview of the silicon packaging strategies adopted by the DarkSide collaboration will be introduced with attention to the mass-production of about 10000 PDMs, corresponding to 200000 SiPMs and to the material selection in terms of cryogenic operation and high radio-purity.

大型基于SiPM的低温光电探测器的包装策略

DarkSide程序旨在使用双相氩气时间投射室进行WIMP直接检测。下一代实验DS-20k将成为超过20吨基准质量的探测器。实验灵敏度的一个关键方面是其光检测技术。DarkSide的合作决定将硅光电倍增管用于其光电检测器模块(PDM)。每个PDM的总有效表面为25厘米 2 前端板能够读取所有SiPM的信号,能够将所有信号聚合到一个模拟输出中,信噪比大于8。在本次演讲中,DarkSide合作将采用的硅封装策略概述在介绍该产品时,要注意大约10000种PDM的批量生产(对应于200000 SiPM),以及在低温操作和高放射纯度方面的材料选择。
