Abstract

The Simons Observatory (SO) will be a CMB survey experiment with three small-aperture telescopes and one large-aperture telescope (the LAT), which will observe from the Atacama Desert in Chile. In total, SO will field over 60,000 TES bolometers in six spectral bands centered between 27 and 280 GHz. The 6 m LAT, targeting the smaller angular scales of the CMB, utilizes a cryogenic receiver (LATR) designed to house up to 13 individual optics tubes. The scientific objectives of the SO project requires these optics tubes to achieve high-throughput optical performance while maintaining exquisite control of systematic effects. We describe the integration and testing program for the LATR optics tubes being carried out to verify the design and assembly of the tubes before deployment. The program includes a quick turn-around single tube test cryostat. We discuss the optical design specifications the tubes for deployment and the suite of optical test equipment prepared for these measurements.

西蒙斯天文台大口径望远镜光学管的集成和测试项目

西蒙斯天文台(SO)将是一个CMB调查实验，它将使用三个小口径望远镜和一个大口径望远镜(LAT)，从智利的阿塔卡马沙漠观测。SO将在以27 GHz至280 GHz为中心的6个频谱带中部署超过6万个TES辐射热计。6米的LAT，目标是CMB较小的角度尺度，利用一个低温接收器(LATR)，设计容纳多达13个单独的光学管。SO项目的科学目标要求这些光学管在保持对系统效果的精细控制的同时实现高通量光学性能。我们描述了正在进行的LATR光学管的集成和测试程序，以验证部署前管的设计和组装。该程序包括一个快速转弯单管低温恒温器测试。我们讨论了光学设计规范，用于部署的管和为这些测量准备的光学测试设备套件。
