摘要:

切伦科夫望远镜阵列(CTA)是一个未来的地基伽马射线天文探测器,将由100多个不同大小的成像大气切伦科夫望远镜组成。$^2$的总反射表面约为10 000 m,需要前所未有的技术努力,以高生产率低成本地生产重量轻且可靠的反射镜基板。我们报告了一个新的反射镜的概念,提出了由INFN开发的CTA,这是基于从一个球形凸模在低压下复制。反射镜基板是一种开放式结构设计,由薄玻璃层制成,在反射镜的前部和后部由钢圆筒间隔开。第一系列的标称尺寸的反射镜已经生产,我们讨论的光学性质的曲率半径和聚焦能力。

英文摘要:

The Cherenkov Telescope Array (CTA) is a future ground-based gamma-ray astronomy detector that will consist of more than 100 Imaging Atmospheric Cherenkov Telescopes of different sizes. The total reflective surface of roughly 10 000 m$^2$ requires unprecedented technological efforts towards a cost-efficient production of light-weight and reliable mirror substrates at high production rate. We report on a new mirror concept proposed for CTA developed by INFN, which is based on the replication from a spherical convex mold under low pressure. The mirror substrate is an open structure design made by thin glass layers at the mirror's front and rear interspaced by steel cylinders. A first series of nominal size mirrors has been produced, for which we discuss the optical properties in terms of radius of curvature and focusing power.
