ACTPol是阿塔卡玛宇宙望远镜上的偏振敏感接收器。ACTPol能够在角分角度尺度下对宇宙微波背景（CMB）的温度和偏振各向异性进行敏感的毫米波长测量。这些测量旨在探索宇宙结构形成的过程，限制或确定中微子质量的总和，探测暗能量，并为许多其他宇宙学测试提供基础。我们介绍了ACTPol观测的第一个季节的概述，重点是第一个探测器阵列的优化和校准，以及详细的天空性能。
ACTPol is the polarization-sensitive receiver on the Atacama Cosmology Telescope. ACTPol enables sensitive millimeter wavelength measurements of the temperature and polarization anisotropies of the Cosmic Microwave Background (CMB) at arcminute angular scales. These measurements are designed to explore the process of cosmic structure formation, constrain or determine the sum of the neutrino masses, probe dark energy, and provide a foundation for a host of other cosmological tests. We present an overview of the first season of ACTPol observations focusing on the optimization and calibration of the first detector array as well as detailing the on-sky performance.
