切伦科夫望远镜阵列天文台（CTAO）由三种类型的望远镜组成：大型（LST），中型（MST）和小型（SST），分布在两个观测点（北部和南部）。对于CTA南“阿尔法配置”，计划建造和安装37（+5）台SST望远镜（在未来升级中可能增加到70台）。SST是由一个国际研究所联合会开发的，该联合会将向CTAO提供SST作为实物捐助。SST依赖于Schwarzschild-Couder双镜多项式光学设计，主镜直径为4 m，并配备了基于SiPM探测器的焦平面相机，覆盖约9°的视场。目前的SST概念通过开发原型双镜ASTRI-Horn切伦科夫望远镜和ASTRI-S SiPM焦平面相机得到验证。在这篇文章中，我们将介绍SST关键技术的概述，SST项目的现状，以及计划的时间表。
The Cherenkov Telescope Array Observatory (CTAO) consists of three types of telescopes: large-sized (LST), mediumsized (MST), and small-sized (SST), distributed in two observing sites (North and South). For the CTA South “Alpha Configuration” the construction and installation of 37 (+5) SST telescopes (a number that could increase up to 70 in future upgrades) are planned. The SSTs are developed by an international consortium of institutes that will provide them as an in-kind contribution to CTAO. The SSTs rely on a Schwarzschild-Couder-like dual-mirror polynomial optical design, with a primary mirror of 4 m diameter, and are equipped with a focal plane camera based on SiPM detectors covering a field of view of ~9°. The current SST concept was validated by developing the prototype dual-mirror ASTRI-Horn Cherenkov telescope and the CHEC-S SiPM focal plane camera. In this contribution, we will present an overview of the SST key technologies, the current status of the SST project, and the planned schedule.
