布鲁诺·凯斯勒基金会生产的近紫外高密度（NUV-HD）SiPM已被用于开发16像素的光学单元，以装备原型施瓦茨希尔德-库德望远镜（pSCT）的焦平面，该望远镜被提议作为切伦科夫望远镜阵列天文台中型望远镜的可能设计。在组装过程之后，对光学单元进行测试和表征，以研究它们在增益和暗计数率方面的性能和均匀性。在这项工作中，我们报告的组装程序和NUV-HD的不同生产的实验室测试和选择，我们所做的最好的质量传感器用于安装在望远镜相机上。目前，36个NUV-HD 3光学单元已成功集成在pSCT相机上，还有64个HAMAMATSU MPPC。pSCT相机的升级预计将在未来几年内完成，届时整个焦平面预计将完全配备FBK NUV-HD 3 SiPM，总像素为11328。
The Near Ultraviolet High Density (NUV-HD) SiPMs produced by Fondazione Bruno Kessler have been employed to develop 16-pixel optical units to equip the focal plane of the prototype Schwarzschild–Couder Telescope (pSCT) proposed as a possible design for the Medium-Sized Telescope of the Cherenkov Telescope Array Observatory. After the assembly procedure, the optical units were tested and characterized to study their performance and homogeneity in terms of gain and dark count rate. In this work, we report on the assembly procedure and on the laboratory tests performed on different production of NUV-HD and the selection we made for the best quality sensors to be used in the installation on the telescope camera. Currently 36 NUV-HD3 optical units have been successfully integrated on the pSCT camera, together with 64 HAMAMATSU MPPCs. An upgrade of the pSCT camera is foreseen over the next years when the full focal plane is expected to be equipped entirely with FBK NUV-HD3 SiPMs, for a total of 11328 pixels.
