摘要
Schwarzschild-Couder 望远镜（SCT）是为切伦科夫望远镜阵列提出的一种望远镜概念。它采用双镜光学设计以消除 视场上的彗差，并采用高密度硅光电倍增管相机（像素分辨率为 4 角分）来记录大气中宇宙射线与伽马射线引发的粒子级联的切伦科夫辐射。原型 SCT（pSCT）由直径 9.7 m 的主镜与具有 1536 像素的部分安装相机组成，已在 Fred Lawrence Whipple 天文台建成。该望远镜于 2019 年 1 月落成，调试工作贯穿 2019 年。我们描述了 2020 年 1 月与 2 月进行的 pSCT 首次观测活动，并展示了以 统计显著性对蟹状星云伽马射线辐射的探测。
