论文摘要
Simons天文台（SO）是一个基于地面的宇宙微波背景（CMB）调查实验，由三个0.5 m的小型伸缩望远镜和一个6 m的大孔望远镜组成，位于辣椒的Atacama沙漠中的5200 m高度。因此，将利用60,000多个过渡边缘传感器（TES）观察27-280 GHz的六个频带中的CMB温度和极化。小孔和大型望远镜接收器（LATR）共有的是300K-4K通用读数安全带（URH），它支持多达600个DC偏置线和24个无线电频率（RF）通道，这些通道由输入和输出相连的电缆和输出相连电缆组成，输入输入器，输入衰减器和自定义高动态型号的40k低量范围读取器（LNAS）上的电缆（LNAS）上的电缆（LNAS）上的电缆读取量（LNAS）上的电缆读取量（LNAS）上的读取量（LNAS）上的电缆（LNAS）上的电缆（LNAS）上的读取量读取了读取的电缆。每个RF通道最多可以读取1000个TES探测器。在本文中，我们将介绍为So部署的初始阶段构建的六个URH的设计和表征。
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that consists of three 0.5 m small-aperture telescopes and one 6 m large-aperture telescope, sited at an elevation of 5200 m in the Atacama Desert in Chile. SO will utilize more than 60,000 transition edge sensors (TES) to observe CMB temperature and polarization in six frequency bands from 27-280 GHz. Common to both the small and large aperture telescope receivers (LATR) is the 300K-4K Universal Readout Harness (URH), which supports up to 600 DC bias lines and 24 radio frequency (RF) channels consisting of input and output coaxial cables, input attenuators and custom high dynamic range 40K low-noise amplifiers (LNAs) on the output readout coaxial cable. Each RF channel can read out up to 1000 TES detectors. In this paper, we will present the design and characterization of the six URHs constructed for the initial phase of SO deployment.
