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的小孔望远镜（SAT）和一个6 m的大孔径望远镜（LAT）组成，位于智利阿塔卡马沙漠的5200 m海拔。为了满足下一代CMB望远镜设置的灵敏度要求，LAT将在7个光学管（OT）中以100 mk的速度部署30,000个过渡边缘传感器（TES）检测器，所有探测器均在大型孔径望远镜接收器（LATR）内。此外，LATR具有在13个OT中扩展到62,000 TE的能力。 LAT将能够对CMB进行高度分辨率的观测，其中探测器带为30、40、90、150、230和280 GHz。为了充分表征该仪器，我们已经严格测试了LATR系统，并表明它可以达到所需的灵敏度水平。我们表明，LATR符合低温和机械要求，并保持低基线读数噪声。
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that consists of three 0.5 m small-aperture telescopes (SATs) and one 6 m large-aperture telescope (LAT), sited at an elevation of 5200 m in the Atacama Desert in Chile. In order to meet the sensitivity requirements set for next-generation CMB telescopes, the LAT will deploy 30,000 transition edge sensor (TES) detectors at 100 mK across 7 optics tubes (OT), all within the Large Aperture Telescope Receiver (LATR). Additionally, the LATR has the capability to expand to 62,000 TES across 13 OTs. The LAT will be capable of making arcminute-resolution observations of the CMB, with detector bands centered at 30, 40, 90, 150, 230, and 280 GHz. We have rigorously tested the LATR systems prior to deployment in order to fully characterize the instrument and show that it can achieve the desired sensitivity levels. We show that the LATR meets cryogenic and mechanical requirements, and maintains acceptably low baseline readout noise.
