黑暗面计划的目标是使用双相氩时间投影室直接探测WIMP。下一代实验DS-20 k将是一个超过20吨基准质量的探测器。实验灵敏度的一个关键方面是它的光检测技术。DarkSide合作决定采用硅光电倍增管作为其光电探测器模块（PDM）。每个PDM包括由前端板读出的25 cm 2的SiPM的总有效表面，该前端板能够将所有信号聚集在单个模拟输出中，信噪比大于8。在这次演讲中，将介绍DarkSide合作所采用的硅封装策略的概述，并注意到大约10000个PDM的大规模生产，对应于200000个SiPM，以及在低温操作和高放射性纯度方面的材料选择。
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.
