伽玛射线切伦科夫望远镜（GCT）是CTA小型望远镜（SST）部分的望远镜之一。基于双镜Schwarzschild-Couder设计，它允许比通常的单镜设计更紧凑的望远镜和相机，它将配备基于硅光电倍增管（SiPM）的紧凑型高能相机（CHEC）。2015年，GCT原型是CTA前景中建造的第一台双镜望远镜，用于记录夜空中的切伦科夫光。此后进行了进一步的测试和观察。本报告描述了GCT的当前状态，为证明其符合CTA要求而进行的测试结果，以及批量生产设计的优化。GCT合作团队包括来自澳大利亚、法国、德国、日本、荷兰和英国的团队，计划于2019-2020年在智利现场安装首批望远镜，作为CTA预生产阶段的一部分。
The Gamma-ray Cherenkov Telescope (GCT) is one of the telescopes proposed for the Small Sized Telescope (SST) section of CTA. Based on a dual-mirror Schwarzschild-Couder design, which allows for more compact telescopes and cameras than the usual single-mirror designs, it will be equipped with a Compact High-Energy Camera (CHEC) based on silicon photomultipliers (SiPM). In 2015, the GCT prototype was the first dual-mirror telescope constructed in the prospect of CTA to record Cherenkov light on the night sky. Further tests and observations have been performed since then. This report describes the current status of the GCT, the results of tests performed to demonstrate its compliance with CTA requirements, and the optimisation of the design for mass production. The GCT collaboration, including teams from Australia, France, Germany, Japan, the Netherlands and the United Kingdom, plans to install the first telescopes on site in Chile for 2019-2020 as part of the CTA pre-production phase.
