阿塔卡马宇宙学望远镜 (ACT) 旨在以弧分分辨率测量宇宙微波背景 (CMB) 的温度各向异性。这是第一个采用 32×32 密排自由空间耦合过渡边缘超导测辐射热计阵列的 CMB 实验。我们描述了用于自主、预定操作的望远镜系统和软件的组织。当与实时数据流和显示相结合时，我们能够通过北美的互联网在智利高原的远程站点操作望远镜。该望远镜在 2007 年季节的数据传输率为 70 GB/天，2008 年升级为三个阵列后，数据传输率将达到 210 GB/天。
The Atacama Cosmology Telescope (ACT) is designed to measure temperature anisotropies of the cosmic microwave background (CMB) at arcminute resolution. It is the first CMB experiment to employ a 32×32 close-packed array of free-space-coupled transition-edge superconducting bolometers. We describe the organization of the telescope systems and software for autonomous, scheduled operations. When paired with real-time data streaming and display, we are able to operate the telescope at the remote site in the Chilean Altiplano via the Internet from North America. The telescope had a data rate of 70 GB/day in the 2007 season, and the 2008 upgrade to three arrays will bring this to 210 GB/day.
