小尺寸望远镜（SST），分布在几平方公里的面积，占主导地位的CTA灵敏度的光子能量范围从几个TeV到超过100 TeV，使非常高的能量伽马射线天空的详细探索。拟议中的望远镜是创新的设计，提供了广阔的视野。其中两个，ASTRI（Astrophysics con Specchi a Tecnologia Replicante Italiana）和GCT（伽马射线切伦科夫望远镜）望远镜，是基于双镜Schwarzschild-Couder光学，主镜直径为4米。第三个是SST-1 M，是Davies-Cotton设计的，有一个直径为4米的镜子。介绍了这些望远镜原型的建造和测试进展情况。SST相机使用硅光电倍增管，并设计了用于优化这些传感器（大气）切伦科夫光性能的放大器和读出/触发电子器件。讨论了摄像机的发展现状。SST子阵列将由CTA南部站点的大约70台望远镜组成。目前的计划执行阵列。
The small size telescopes (SSTs), spread over an area of several square km, dominate the CTA sensitivity in the photon energy range from a few TeV to over 100 TeV, enabling for the detailed exploration of the very high energy gamma-ray sky. The proposed telescopes are innovative designs providing a wide field of view. Two of them, the ASTRI (Astrophysics con Specchi a Tecnologia Replicante Italiana) and the GCT (Gamma-ray Cherenkov Telescope) telescopes, are based on dual mirror Schwarzschild-Couder optics, with primary mirror diameters of 4 m. The third, SST-1M, is a Davies-Cotton design with a 4 m diameter mirror. Progress with the construction and testing of prototypes of these telescopes is presented. The SST cameras use silicon photomultipliers, with preamplifier and readout/trigger electronics designed to optimize the performance of these sensors for (atmospheric) Cherenkov light. The status of the camera developments is discussed. The SST sub-array will consist of about 70 telescopes at the CTA southern site. Current plans for the implementation of the array are presented.
