摘要
SST-1M是一种小型望远镜（SST），旨在为伽马射线天体物理学，特别是能量超过几个TeV的伽马射线，提供一种高性价比且高性能的解决方案。其目标是将该望远镜集成到一个由类似仪器组成的阵列中，利用其轻量化设计、抗震性以及成熟的Davies-Cotton结构。此外，其光学系统设计为无需保护罩即可运行，能够承受海拔2000米以上山区典型的恶劣大气条件。SST-1M采用基于硅光电倍增管（SiPMs）的全数字化相机系统。该相机能够数字化来自紫外-光学光探测器的所有信号，从而允许实现各种触发和数据分析方法。我们详细介绍了设计、原型制作和验证该系统的过程，确保其满足伽马射线探测和性能的严格要求。一个SST-1M立体系统目前正在捷克共和国海拔500米的Ondřejov天文台运行并收集数据。该系统的初步结果令人鼓舞。一篇即将发表的论文将提供望远镜在真实条件下探测伽马射线和运行性能的全面分析。
