我们已经开发了一个原型六角形聚光器的切伦科夫望远镜阵列的大尺寸望远镜。为了最大化焦平面相机像素对大气切伦科夫光子的光电探测效率并降低能量阈值，已经开发了具有92-99%的非常高的反射率的镜面膜来覆盖光集中器的内表面。原型在最重要的入射角下具有约95至105%的相对阳极灵敏度（其可粗略地视为收集效率）。聚光器原型的设计，模拟，生产过程和性能测量的报告。
We have developed a prototype hexagonal light concentrator for the Large-Sized Telescopes of the Cherenkov Telescope Array. To maximize the photodetection efficiency of the focal-plane camera pixels for atmospheric Cherenkov photons and to lower the energy threshold, a specular film with a very high reflectance of 92–99% has been developed to cover the inner surfaces of the light concentrators. The prototype has a relative anode sensitivity (which can be roughly regarded as collection efficiency) of about 95 to 105% at the most important angles of incidence. The design, simulation, production procedure, and performance measurements of the light-concentrator prototype are reported.
