论文摘要
在过去的十年中，硅光电塑料（SIPM）在实验和应用中获得了地形，在这些实验和应用中，在几十年来，光电塑料管一直是主要的光传感器。成像大气Cherenkov望远镜（IACTS）具有很高的能量（VHE，E $> $ 50 GEV）Gamma-ray天文学正在经历相同的过程。到目前为止，事实是使用SIPMS的唯一IACT。在Cherenkov望远镜阵列（CTA）中，下一代VHE伽马射线天文台，计划建造至少有70个配备sipms的望远镜。最初的原型已经建成，现在正在委托。在这里，我们讨论了在Vhe gamma-ray天文学中使用sipms的一些优点和缺点，并简要概述了与sipms在IACTS中使用有关的不同发展。
In the last ten years silicon photomultipliers (SiPMs) have gained terrain in experiments and applications in which photomultiplier tubes have been the dominant photosensors during decades. Imaging Atmospheric Cherenkov Telescopes (IACTs) for very high energy (VHE, E$>$50 GeV) gamma-ray astronomy are experiencing the same process. Until now FACT was the only IACT using SiPMs. In the Cherenkov Telescope Array (CTA), the next-generation VHE gamma-ray observatory, at least 70 telescopes equipped with SiPMs are planned to be built. The first prototypes have already been constructed and are now being commissioned. Here we discuss some of the advantages and drawbacks of using SiPMs in VHE gamma-ray astronomy and provide a brief overview of different developments related to the use of SiPMs in IACTs.
