论文摘要
SST-1M是直径为4米的镜子Davies-Cotton伽马射线望远镜。它旨在覆盖高于500 GEV的能源范围,并成为一系列望远镜的一部分,该望远镜距离为150-200 m。它的创新相机以大面积的六角硅照相仪为特色,作为光子探测器以及完全数字扳机和读取系统。在这里,提出了策略及其校准方法,以及获得的结果。特别是,在第一个相机原型上展示了OFF和现场校准策略。描述了相机在充电和时间分辨率方面的性能。
The SST-1M is a 4-m diameter mirror Davies-Cotton gamma-ray telescope. It has been designed to cover the energy range above 500 GeV and to be part of an array of telescopes separated by 150-200 m. Its innovative camera is featuring large area hexagonal silicon photo-multipliers as photon detectors and a fully digital trigger and readout system. Here, the strategy and the methods for its calibration are presented, together with the obtained results. In particular, the off and on-site calibration strategies are demonstrated on the first camera prototype. The performances of the camera in terms of charge and time resolution are described.
