摘要:

切伦科夫望远镜阵列(Cherenkov Telescope Array,CTA)是一个计划中的甚高能伽马射线天文观测站。它将由几十个不同尺寸的望远镜组成,总镜面面积高达10,000平方米。目前安装的大多数镜子要么是抛光玻璃镜,要么是金刚石铝镜,这两种都是劳动密集型技术。对于CTA,已经开发了几种新技术,用于快速、经济高效地生产重量轻、可靠的反射镜基板,其中大部分已经开始工业预生产。此外,新的或改进的铝基和介电表面涂层已被开发,以增加反射镜的寿命相比,目前切伦科夫望远镜仪器的反射率。

英文摘要:

The Cherenkov Telescope Array (CTA) is a planned observatory for very-high energy gamma-ray astronomy. It will consist of several tens of telescopes of different sizes, with a total mirror area of up to 10,000 square meters. Most mirrors of current installations are either polished glass mirrors or diamond-turned aluminium mirrors, both labour intensive technologies. For CTA, several new technologies for a fast and cost-efficient production of light-weight and reliable mirror substrates have been developed and industrial pre-production has started for most of them. In addition, new or improved aluminium-based and dielectric surface coatings have been developed to increase the reflectance over the lifetime of the mirrors compared to those of current Cherenkov telescope instruments.
