Abstract

The Simons Observatory is a suite of instruments sensitive to temperature and polarization of the cosmic microwave background. Five telescopes will host over 60,000 highly multiplexed transition edge sensor (TES) detectors. The universal focal plane modules (UFMs) package multichroic TES detectors with microwave multiplexing electronics compatible with all five receivers. The low-frequency arrays are lenslet-coupled sinuous antennas sensitive to 30 and 40 GHz. The mid-frequency and ultra-high-frequency UFMs are horn-coupled orthomode transducer arrays sensitive to 90/150 GHz and 225/280 GHz, respectively. Here we present the design, assembly details, and initial results of the first UFM.

组装开发的西蒙斯天文台焦平面读出模块

西蒙斯天文台是一套对温度和宇宙微波背景极化敏感的仪器。五台望远镜将容纳超过6万个高复用过渡边缘传感器(TES)探测器。通用焦平面模块(ufm)封装多频TES探测器与微波多路复用电子兼容所有五个接收器。低频阵列是透镜耦合的正弦天线，对30ghz和40ghz敏感。中频和超高频ufm分别是灵敏度为90/150 GHz和225/280 GHz的角耦合正交换能器阵列。在这里，我们展示了第一个UFM的设计、装配细节和初步结果。
