切伦科夫望远镜阵列（CTA）是下一个主要的伽玛射线天文学地面天文台。使用CTA可以在几十GeV到100TeV的高能伽玛射线范围内研究伽玛射线源，其灵敏度比现有的仪器高10倍。我们讨论了美国对CTA的贡献，包括用史瓦西-库德（SC）光学成像大气切伦科夫望远镜。SC望远镜的主要特点是8度的宽视场，一个带有硅光电倍增管作为光子探测器的精细像素相机，以及一个紧凑且节能的1 GS/s读出器。本文讨论了光学系统和摄像机的发展进展。
The Cherenkov Telescope Array (CTA) is the next major ground-based observatory for gamma-ray astronomy. With CTA gamma-ray sources will be studied in the very-high energy gamma-ray range of a few tens of GeV to 100TeV with up to ten times better sensitivity than available with current generation instruments. We discuss the proposed US contribution to CTA that comprises imaging atmospheric Cherenkov telescope with Schwarzschild-Couder (SC) optics. Key features of the SC telescope are a wide field of view of eight degrees, a finely pixelated camera with silicon photomultipliers as photon detectors, and a compact and power efficient 1 GS/s readout. The progress in both the optical system and camera development are discussed in this paper.
