硅光电倍增管（SiPM）是探测高能大气簇射中发出的微弱而短暂的切伦科夫光的优秀器件，因此适用于成像空气切伦科夫望远镜。布鲁诺·凯斯勒基金会（FBK）与INFN合作生产的高密度近紫外线SiPM（NUV-HD 3）用于装备光学模块，用于在切伦科夫望远镜阵列项目的框架内对施瓦茨希尔德-库德望远镜相机原型进行可能的升级。SiPM是基于40×40 μm2微单元的6×6 mm 2器件，针对NUV波长的光检测进行了优化。组装了40多个光学模块，每个模块由4×4 SiPM阵列组成。在这方面的贡献，我们报告的发展和组装的光学模块，他们的验证和集成在相机。
Silicon Photomultipliers (SiPMs) are excellent devices to detect the faint and short Cherenkov light emitted in high energy atmospheric showers, and therefore suitable for use in imaging air Cherenkov Telescopes. The high density Near Ultraviolet Violet SiPMs (NUV-HD3) produced by Fondazione Bruno Kessler (FBK) in collaboration with INFN were used to equip optical modules for a possible upgrade of the Schwarzschild-Couder Telescope camera prototype, in the framework of the Cherenkov Telescope Array project. SiPMs are 6×6 mm2 devices based on 40×40 μm2 microcells optimized for photo-detection at the NUV wavelengths. More than 40 optical modules, each composed by a 4×4 array of SiPMs, were assembled. In this contribution we report on the development and on the assembly of the optical modules, their validation and integration in the camera.
