论文摘要

Simons天文台（SO）是一套对温度和宇宙微波背景（CMB）极化敏感的仪器，位于智利阿塔卡马沙漠的Cerro Toco。五个望远镜，一个望远镜的望远镜和四个小孔望远镜，将容纳大约70,000个高度多路复用的过渡边缘传感器（TES）检测器，该探测器以100 mk运行。每个焦平面模块（UFM）在微波多路复用（UMUX）读出电路中与微波谐振器夫妇夫妻夫妻夫妻夫妻夫妇。在检测器集成之前，将100 MK Umux组件包装到多路复用模块（UMMS）中，这些模块被独立验证以确保它们符合性能规格。在这里，我们介绍了这些UMM读数软件包的组装开发，用于中频（90/150 GHz）和超高频（220/280 GHz）UFM。

The Simons Observatory (SO) is a suite of instruments sensitive to temperature and polarization of the cosmic microwave background (CMB) to be located at Cerro Toco in the Atacama Desert in Chile. Five telescopes, one large aperture telescope and four small aperture telescopes, will host roughly 70,000 highly multiplexed transition edge sensor (TES) detectors operated at 100 mK. Each SO focal plane module (UFM) couples 1,764 TESes to microwave resonators in a microwave multiplexing (uMux) readout circuit. Before detector integration, the 100 mK uMux components are packaged into multiplexing modules (UMMs), which are independently validated to ensure they meet SO performance specifications. Here we present the assembly developments of these UMM readout packages for mid frequency (90/150 GHz) and ultra high frequency (220/280 GHz) UFMs.
