Abstract

The Simons Observatory (SO) is a cosmic microwave background (CMB) experiment located in the Atacama Desert in Chile that will make precise temperature and polarization measurements over six spectral bands ranging from 27 to 285 GHz. Three small aperture telescopes (SATs) and one large aperture telescope (LAT) will house \(\sim\)60,000 detectors and cover angular scales between one arcminute and tens of degrees. We present the performance of the dichroic, low-frequency (LF) lenslet-coupled sinuous antenna transition-edge sensor (TES) bolometer arrays with bands centered at 27 and 39 GHz. The LF focal plane will primarily characterize Galactic synchrotron emission as a critical part of foreground subtraction from CMB data. We will discuss the design, optimization, and current testing status of these pixels.

西蒙斯天文台：低频探测器的设计、优化和性能

西蒙斯天文台（SO）是位于智利阿塔卡马沙漠的宇宙微波背景（CMB）实验，将在27至285 GHz的六个光谱波段进行精确的温度和偏振测量。三个小口径望远镜（SATs）和一个大口径望远镜（LAT）将容纳\(\sim\) 60,000个探测器，覆盖角分到几十度之间的尺度。本文介绍了以27 GHz和39 GHz为中心的二向色、低频（LF）透镜耦合正弦天线过渡边缘传感器（TES）辐射热计阵列的性能。LF焦平面将主要表征银河同步辐射，作为CMB数据前景减法的关键部分。我们将讨论这些像素的设计、优化和当前测试状态。
