原型施瓦兹希尔德-库德望远镜（pSCT）是切伦科夫望远镜阵列中中型望远镜的候选者。pSCT是基于双镜光学设计，减少了板规模，并允许使用硅光电倍增管作为光电探测器。原型pSCT相机目前只有中央部分装有25个相机模块（1600像素），提供2.68度视场（FoV）。相机电子器件基于定制TARGET（具有GSa/s采样和事件触发的TeV阵列读出）专用集成电路。现场可编程门阵列以每秒千兆采样的速度对输入信号进行采样。一个背板提供了相机范围的触发。正在升级pSCT相机，以完全填充焦平面。这将使像素数增加到11，328，背板数增加到9，FoV增加到8.04 deg。在这里，我们对pSCT相机进行了详细的描述，包括基本概念，机械设计，探测器，电子学，当前状态和第一盏灯。
The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a dual-mirror optics design that reduces the plate scale and allows for the use of silicon photomultipliers as photodetectors. The prototype pSCT camera currently has only the central sector instrumented with 25 camera modules (1600 pixels), providing a 2.68-deg field of view (FoV). The camera electronics are based on custom TARGET (TeV array readout with GSa/s sampling and event trigger) application-specific integrated circuits. Field programmable gate arrays sample incoming signals at a gigasample per second. A single backplane provides camera-wide triggers. An upgrade of the pSCT camera that will fully populate the focal plane is in progress. This will increase the number of pixels to 11,328, the number of backplanes to 9, and the FoV to 8.04 deg. Here, we give a detailed description of the pSCT camera, including the basic concept, mechanical design, detectors, electronics, current status, and first light.
