摘要
SST-1M 望远镜是正在建设中的原型机之一，拟作为未来切伦科夫望远镜阵列的一部分。它采用标准的 Davis-Cotton 光学与望远镜结构设计，碟面直径为 4 米，具有 9 度的大视场。其创新的相机设计由包含 1296 像素的光子探测面组成，涵盖入射窗、光收集器、硅光电倍增管和前置放大级，并配备全数字读出与触发电子学系统 DigiCam。在本文中，我们对为 SST-1M 原型机设计的分析链进行了概述。特别地，我们重点关注定标策略，该策略用于将 DigiCam 记录的 SiPM 信号转换为切伦科夫图像分析所需的物理量。该定标基于一个在线反馈系统以稳定 SiPM 的增益，并利用在原型机正常运行期间采集的专用事件（暗计数、 pedestal 和闪光事件）来完成。
