论文摘要
Schwarzschild-Couder望远镜（PSCT）的原型是Cherenkov望远镜阵列中中型望远镜的候选者。 PSCT基于一种新型的双镜式光学设计，该设计可降低板尺，并允许将硅光电培养基用作光电探测器。 PSCT摄像机目前仅具有带有25个相机模块（1600个像素）的中央扇区仪器，提供了2.68 $^{\ CRICT} $视图（FOV）。相机电子设备基于自定义目标（带有GSA/S采样和事件触发器的TEV阵列读数）应用程序特定集成电路。现场可编程栅极阵列以每秒的gigasample示例传入信号。单个背板提供范围范围的触发器。 PSCT相机的升级正在进行中，这将完全填充焦平面。这将将像素的数量增加到11,328，后平面的数量和9 fov将其增加到8.04 $^{\ circ} $。在这里，我们提供了PSCT摄像机的详细说明，包括基本概念，机械设计，探测器，电子，当前状态和第一光。
The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a novel dual mirror optics design which reduces the plate scale and allows for the use of silicon photomultipliers as photodetectors. The prototype pSCT camera currently has only the central sector instrumented with 25 camera modules (1600 pixels), providing a 2.68$^{\circ}$ 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 is in progress, which will fully populate the focal plane. This will increase the number of pixels to 11,328, the number of backplanes to 9, and the FoV to 8.04$^{\circ}$. Here we give a detailed description of the pSCT camera, including the basic concept, mechanical design, detectors, electronics, current status and first light.
