论文摘要
当前使用液相的贵重气体进行直接暗物质搜索和中微子物理学的探测器需要大面积的光传感器。基于硅的照片检测器是创新的收集设备，代表了这些研究领域的成功技术。 Darkside协作开始了SIPM技术的专门开发和定制，以达到其特定需求，从而导致了20x20 cm^2的大型表面模块的设计，生产和组装，称为Darkside-20K实验的照片检测单元。需要生产大量此类设备，以覆盖Darkside-20k检测器内的活性表面的20 m^2，需要强大的测试和验证过程。为了符合此要求，在Infn-Naples实验室设计和委托了针对光泽测试的专用测试设施。第一次调试测试在2021年成功进行。此后，进行了许多测试活动。报告了该设施的详细描述以及一些测试的结果。
Current generation of detectors using noble gases in liquid phase for direct dark matter search and neutrino physics need large area photosensors. Silicon based photo-detectors are innovative light collecting devices and represent a successful technology in these research fields. The DarkSide collaboration started a dedicated development and customization of SiPM technology for its specific needs resulting in the design, production and assembly of large surface modules of 20x20 cm^2 named Photo Detection Unit for the DarkSide-20k experiment. Production of a large number of such devices, as needed to cover about 20 m^2 of active surface inside the DarkSide-20k detector, requires a robust testing and validation process. In order to match this requirement a dedicated test facility for the photosensor test was designed and commissioned at INFN-Naples laboratory. The first commissioning test was successfully performed in 2021. Since then a number of testing campaigns were performed. Detailed description of the facility is reported as well as results of some tests.
