标题： Design and Deployment of a Multichroic Polarimeter Array on the Atacama Cosmology Telescope

摘要： 我们介绍了覆盖90 GHz和146 GHz宇宙微波背景（CMB）频段的多频带偏振计阵列及其近期部署于阿塔卡马宇宙学望远镜（ACT）上的宽带光学系统的初步天文观测性能，包括其在光束和频带方面的表现。 这些组成像素是由NIST制造的喇叭天线耦合多频带偏振计。 该阵列通过一套由三块硅透镜组成的系统与ACT望远镜相连，这些透镜采用了新型宽带超材料减反射涂层。 该接收器代表了首个用于CMB实验的多频带探测器阵列，并为下一代CMB实验中广泛使用多频带探测器和宽带光学系统铺平了道路。 显示英文摘要

摘要： We present the design and the preliminary on sky performance with respect to beams and pass-bands of a multichroic polarimeter array covering the 90 and 146 GHz Cosmic Microwave Background (CMB) bands and its enabling broadband optical system recently deployed on the Atacama Cosmology Telescope (ACT). The constituent pixels are feedhorn-coupled multichroic polarimeters fabricated at NIST. This array is coupled to the ACT telescope via a set of three silicon lenses incorporating novel broad-band metamaterial anti-reflection coatings. This receiver represents the first multichroic detector array deployed for a CMB experiment and paves the way for the extensive use of multichroic detectors and broadband optical systems in the next generation of CMB experiments.
