在地基γ射线天文学的历史上，双镜，非球面，消球差Schwarzschild-Couder光学系统的轴上性能首次在9：7米孔径成像大气切伦科夫望远镜中得到了证明。原型施瓦兹希尔德-库德望远镜（pSCT）的新颖设计是出于下一代切伦科夫望远镜阵列（CTA）天文台的需要，该天文台有能力同时进行宽（≥ 8 °）视场观测和大气级联的上级成像（分辨率为每像素0：067或更高）。pSCT设计，如果在CTA装置中实施，有可能显着提高X射线角分辨率和天文台的离轴灵敏度，接近该技术的理论极限，从而对CTA天文台天空调查计划产生重大影响，对初始定位知之甚少的多信使瞬变的后续观测，以及扩展X射线源的空间分辨光谱研究。这篇文章报道了pSCT具有挑战性的分段非球面主镜和次镜的初始对准程序和点扩散函数结果。
For the first time in the history of ground-based y-ray astronomy, the on-axis performance of the dual mirror, aspheric, aplanatic Schwarzschild-Couder optical system has been demonstrated in a 9:7-m aperture imaging atmospheric Cherenkov telescope. The novel design of the prototype Schwarzschild-Couder Telescope (pSCT) is motivated by the need of the next-generation Cherenkov Telescope Array (CTA) observatory to have the ability to perform wide (≥8°) field-of-view observations simultaneously with superior imaging of atmospheric cascades (resolution of 0:067 per pixel or better). The pSCT design, if implemented in the CTA installation, has the potential to improve significantly both the x-ray angular resolution and the off-axis sensitivity of the observatory, reaching nearly the theoretical limit of the technique and thereby making a major impact on the CTA observatory sky survey programs, follow-up observations of multi-messenger transients with poorly known initial localization, as well as on the spatially resolved spectroscopic studies of extended x-ray sources. This contribution reports on the initial alignment procedures and point-spread-function results for the challenging segmented aspheric primary and secondary mirrors of the pSCT.
