2015年6月初，位于亚利桑那州南部的弗雷德·劳伦斯维普莱天文台开始建造原型施瓦兹希尔德-库德望远镜（pSCT），作为切伦科夫望远镜阵列（CTA）的候选中型望远镜。与目前的Davies-Cotton望远镜相比，这种具有消球差双镜光学系统的新型仪器将提供更宽的视场和更高的角分辨率。此外，相机的缩小版尺寸允许使用高度集成的光子探测器，如硅光电倍增器。作为CTA的一部分，这一设计有可能大大提高下一代甚高能（E>60 GeV）伽马射线天文学地面观测站的性能。在这方面的贡献，我们提出的pSCT的光学和对准系统的设计和性能。
The construction of a prototype Schwarzschild-Couder telescope (pSCT) started in early June 2015 at the Fred Lawrence Whipple Observatory in Southern Arizona, as a candidate medium-sized telescope for the Cherenkov Telescope Array (CTA). Compared to current Davies-Cotton telescopes, this novel instrument with an aplanatic two-mirror optical system will offer a wider field-of-view and improved angular resolution. In addition, the reduced plate scale of the camera allows the use of highly-integrated photon detectors such as silicon photo multipliers. As part of CTA, this design has the potential to greatly improve the performance of the next generation ground-based observatory for very high-energy (E>60 GeV) gamma-ray astronomy. In this contribution we present the design and performance of both optical and alignment systems of the pSCT.
