论文摘要

在基于地面的$γ$ ray天文学的历史上,双镜的轴上表现,无球,平面性的Schwarzschild-couder光学系统已在$ 9.7 $ -MM的Aperture Imageing Mastioneric Mastioneric Mastioneric Cherenkov望远镜中得到了证明。原型Schwarzschild-Couder望远镜(PSCT)的新颖设计是由下一代Cherenkov望远镜阵列(CTA)观测值进行的,具有宽广泛的能力($ \ geq 8^{\ circ} $),并具有同时与杂物相关的杂物($ \ ge) $ 0.067^{\ circ} $每个像素或更好)。 PSCT设计如果在CTA安装中实施,则有可能显着提高$γ$ - 射线的角度分辨率和观测站的敏感性,几乎达到了该技术的理论限制,从而对CTA天空调查程序进行了重大影响,从而对差异的定位进行了对不良的定位,并对差异进行了定位。扩展的$γ$ - 射线来源的研究。该贡献报告了PSCT的具有挑战性分段的非球面主要和次级镜子的初始对准程序和点传播功能结果。

For the first time in the history of ground-based $γ$-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 ($\geq 8^{\circ}$) field-of-view observations simultaneously with superior imaging of atmospheric cascades (resolution of $0.067^{\circ}$ per pixel or better). The pSCT design, if implemented in the CTA installation, has the potential to improve significantly both the $γ$-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 $γ$-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.
