阿塔卡马宇宙学望远镜旨在测量宇宙微波背景中的小尺度各向异性，并通过苏尼亚耶夫-泽尔多维奇效应探测星系团。该仪器位于阿塔卡马沙漠的托科山，海拔5190米。 6 m 离轴格里高利望远镜为新型低温接收器（毫米测辐射热计阵列相机）提供信号。该接收器具有三个 1000 元件的过渡边缘传感器测辐射热计阵列，可在 148 GHz、218 GHz 和 277 GHz 频率下进行观测。每个探测器阵列均由自由空间毫米波光学器件供电。每个频段的视场约为 22' × 26'。该望远镜于 2007 年投入使用，现已完成运行的第三年。我们讨论了望远镜、相机和相关系统的主要部件，并总结了仪器性能。
The Atacama Cosmology Telescope was designed to measure small-scale anisotropies in the cosmic microwave background and detect galaxy clusters through the Sunyaev–Zel’dovich effect. The instrument is located on Cerro Toco in the Atacama Desert, at an altitude of 5190 m. A 6 m off-axis Gregorian telescope feeds a new type of cryogenic receiver, the Millimeter Bolometer Array Camera. The receiver features three 1000-element arrays of transition-edge sensor bolometers for observations at 148 GHz, 218 GHz, and 277 GHz. Each detector array is fed by free space millimeter-wave optics. Each frequency band has a field of view of approximately 22′ × 26′. The telescope was commissioned in 2007 and has completed its third year of operations. We discuss the major components of the telescope, camera, and related systems, and summarize the instrument performance.
