切伦科夫望远镜阵列天文台（CTAO）是下一代地基甚高能伽马射线天文学设施。CTAO将作为一个开放的天文台运营。切伦科夫望远镜阵列CTA将在北方和南方两个地点提供全天空覆盖，比现有仪器提高一个数量级的灵敏度，伽马射线能量覆盖范围从20 GeV到300 TeV。CTA将使用由三种类型的望远镜组成的望远镜阵列，优化以覆盖不同的能量范围。覆盖最低能量的大型望远镜提供快速回转能力，用于瞬态的后续工作。关键科学项目（KSPs）的开发是CTAO观测计划的重要组成部分，在运行的第一个十年，提供遗留数据集，如调查或对关键目标的深度观测。
The Cherenkov Telescope Array Observatory (CTAO) is a next-generation facility for ground-based very high energy gamma ray astronomy. CTAO will be operated as an open observatory. With two sites, in the northern and southern hemispheres, the Cherenkov Telescope Array CTA will provide full-sky coverage, improving sensitivity by an order of magnitude over current instruments, with a wide gamma ray energy coverage from 20 GeV to 300 TeV. CTA will use telescope arrays composed of three types of telescopes, optimized to cover different energy ranges. The large telescopes covering the lowest energies provide rapid slewing capability, for follow-up of transients. Key Science Projects (KSPs) are developed to form a significant part of the CTAO observing program during the first decade of operation, providing legacy data sets such as surveys or deep observations of key targets.
