切伦科夫望远镜阵列（CTA）是地基甚高能伽马射线天文学的主要下一代天文台。它将提高现有地面仪器的灵敏度5至20倍，这取决于能量，在40年的能量（从20 GeV到300 TeV）中，大大提高了它们的角度和能量分辨率。这一成就将有可能通过使用数十个成像切伦科夫望远镜的三个连续的大小。它们将被安排成两个阵列，每个半球一个，分别位于拉帕尔马岛（西班牙）和帕拉纳尔（智利）。我们在这里提出的优化和最终的望远镜阵列CTA的网站，以及他们的预期性能，从三个不同的大规模蒙特卡洛生产的分析。(C)2019爱思唯尔B.V.保留所有权利。
The Cherenkov Telescope Array (CTA) is the major next-generation observatory for ground-based veryhigh-energy gamma-ray astronomy. It will improve the sensitivity of current ground-based instruments by a factor of five to twenty, depending on the energy, greatly improving both their angular and energy resolutions over four decades in energy (from 20 GeV to 300 TeV). This achievement will be possible by using tens of imaging Cherenkov telescopes of three successive sizes. They will be arranged into two arrays, one per hemisphere, located on the La Palma island (Spain) and in Paranal (Chile). We present here the optimised and final telescope arrays for both CTA sites, as well as their foreseen performance, resulting from the analysis of three different large-scale Monte Carlo productions.
