自50多年前诞生以来，光电倍增管技术一直是大气切伦科夫望远镜成像技术的首选光电探测器。最近，新类型的光电传感器正在考虑下一代切伦科夫望远镜阵列。据设想，该阵列将部分由使用Schwarzschild-Couder双镜设计的望远镜组成，这种设计以前从未建造过，这显着改善了光学性能。这种新型光学设计的相机具有小的板尺度，使得能够使用紧凑的光电传感器。我们提出了一个广泛的和详细的研究正在考虑的两个最有前途的设备，这个望远镜的设计：硅光电倍增管和多阳极光电倍增管。我们评估了它们对γ射线簇射成像的最关键性能特征，并以一种连贯的方式展示了我们的结果，以清楚地评估这两种类型的设备在GeV-TeV γ射线天文学背景下必须提供的优点和缺点。
Photomultiplier tube technology has been the photodetector of choice for the technique of imaging atmospheric Cherenkov telescopes since its birth more than 50 years ago. Recently, new types of photosensors are being contemplated for the next generation Cherenkov Telescope Array. It is envisioned that the array will be partly composed of telescopes using a Schwarzschild-Couder two mirror design never built before which has significantly improved optics. The camera of this novel optical design has a small plate scale which enables the use of compact photosensors. We present an extensive and detailed study of the two most promising devices being considered for this telescope design: the silicon photomultiplier and the multi-anode photomultiplier tube. We evaluated their most critical performance characteristics for imaging γ-ray showers, and we present our results in a cohesive manner to clearly evaluate the advantages and disadvantages that both types of device have to offer in the context of GeV-TeV γ-ray astronomy.
