南极望远镜（英语：South Pole Telescope，缩写：SPT）是一个毫米波长望远镜，用于高精度测量宇宙微波背景辐射（英语：Cosmic microwave background）。SPT以大口径测量CMB的温度和偏振，从而生成对天空中各种角度范围内的信号敏感的高分辨率地图。有了这些数据，SPT有可能进行广泛的宇宙学测量。这些包括限制大质量中微子对大尺度结构形成的影响，以及在未来寻找暴胀引力波时从CMB偏振数据中清除银河和宇宙学前景。SPT于2017年1月开始使用新的接收器（SPT-3G）进行观测，该接收器包含约16，000个偏振敏感的过渡边缘传感器测辐射热计。几项关键技术的发展使这种大格式焦平面成为可能，包括探测器、读出电子器件和大型毫米波长光学器件的进步。我们将讨论这些技术在SPT-3G接收机中的实现以及它们所面临的挑战。2017年底，所有这三项技术的实现都进行了修改，以优化总体性能。这里，我们介绍了SPT-3G接收机的当前仪器状态。
The South Pole Telescope (SPT) is a millimeter-wavelength telescope designed for high-precision measurements of the cosmic microwave background (CMB). The SPT measures both the temperature and polarization of the CMB with a large aperture, resulting in high resolution maps sensitive to signals across a wide range of angular scales on the sky. With these data, the SPT has the potential to make a broad range of cosmological measurements. These include constraining the effect of massive neutrinos on large-scale structure formation as well as cleaning galactic and cosmological foregrounds from CMB polarization data in future searches for inflationary gravitational waves. The SPT began observing in January 2017 with a new receiver (SPT-3G) containing ~16,000 polarization-sensitive transition-edge sensor bolometers. Several key technology developments have enabled this large-format focal plane, including advances in detectors, readout electronics, and large millimeter-wavelength optics. We discuss the implementation of these technologies in the SPT-3G receiver as well as the challenges they presented. In late 2017 the implementations of all three of these technologies were modified to optimize total performance. Here, we present the current instrument status of the SPT-3G receiver.
