摘要
施瓦西-库德望远镜（SCT）是切伦科夫望远镜阵列中型望远镜的一个提案。其概念基于双镜光学系统，旨在相对于单镜 Davies-Cotton 方案改善望远镜视场与图像分辨率。SCT 相机计划由 177 个光电探测模块组成，每个模块由 64 个硅光电倍增管（SiPM）像素构成。由 Fondazione Bruno Kessler（FBK）与 INFN 合作生产的第三代 高密度近紫外 SiPM（NUV-HD3）已被用于装备将集成到 SCT 原型（pSCT）相机升级件上的光学单元。每个光学单元由 16 个 NUV-HD3 SiPM 阵列与前端电子学耦合而成，该前端电子学设计用于使用 TARGET-7 ASIC 进行全波形纳秒读出与数字化。若干光学单元已在 INFN 的实验室中组装并测试，并已集成到 pSCT 望远镜的相机上，该望远镜目前正在 Fred Lawrence Whipple 天文台运行。在本报告中，我们介绍了目前正在 pSCT 相机上获取数据的光学单元的研制、组装与标定。
