用于Schwarzschild-Couder Cherenkov望远镜的硅光电倍增器相机

Silicon Photomultiplier Camera for Schwarzschild-Couder Cherenkov Telescopes

J. Vandenbroucke

摘要:

切伦科夫望远镜阵列(Cherenkov Telescope Array,CTA)是一个大气切伦科夫天文台,它将以极高能量的伽马射线对宇宙进行成像。CTA将研究宇宙中最高能量的粒子加速器,并可能确认暗物质的粒子性质。我们设计了一种创新的Schwarzschild-Couder望远镜,它使用两个反射镜在宽视场内实现出色的光学性能。双反射镜光学器件的小板尺度使得使用包括硅光电倍增器和TARGET专用集成电路的现代技术的紧凑型相机能够以适度的重量、体积、成本和功耗读出11,328个通道的精细像素化焦平面。摄像机的设计是分层和模块化的,在每个级别,使强大的建设,操作和维护。一个原型望远镜正在建造中,将在亚利桑那州的VERITAS基地投入使用。一组这样的望远镜将在CTA的核心能量范围内提供出色的角分辨率和灵敏度,从100 GeV到10 TeV。

英文摘要:

The Cherenkov Telescope Array (CTA) is an atmospheric Cherenkov observatory that will image the cosmos in very-high-energy gamma rays. CTA will study the highest-energy particle accelerators in the Universe and potentially confirm the particle nature of dark matter. We have designed an innovative Schwarzschild-Couder telescope which uses two mirrors to achieve excellent optical performance across a wide field of view. The small plate scale of the dual-mirror optics enables a compact camera which uses modern technology including silicon photomultipliers and the TARGET application-specific integrated circuit to read out a finely pixelated focal plane of 11,328 channels with modest weight, volume, cost, and power consumption. The camera design is hierarchical and modular at each level, enabling robust construction, operation, and maintenance. A prototype telescope is under construction and will be commissioned at the VERITAS site in Arizona. An array of such telescopes will provide excellent angular resolution and sensitivity in the core energy range of CTA, from 100 GeV to 10 TeV.
