摘要:

在这一过程中,我们提出的仪器系统的影响西蒙斯观测(SO)与探测器系统及其相互作用与完整的SO实验系统的研究。天文台将于六个频带内测量宇宙微波背景的温度和极化各向异性,频带中心由27吉赫至270吉赫。我们探讨的影响,包括强度偏振泄漏由于耦合光学,测辐射热计的非线性,未校准的测辐射热计的增益变化,和读出串扰。我们模拟信号污染的水平,讨论建议的缓解方案,并提出仪器要求,通知SO和未来的CMB项目的设计。

英文摘要:

In this proceeding, we present studies of instrumental systematic effects for the Simons Obsevatory (SO) that are associated with the detector system and its interaction with the full SO experimental systems. SO will measure the Cosmic Microwave Background (CMB) temperature and polarization anisotropies over a wide range of angular scales in six bands with bandcenters spanning from 27 GHz to 270 GHz. We explore effects including intensity-to-polarization leakage due to coupling optics, bolometer nonlinearity, uncalibrated gain variations of bolometers, and readout crosstalk. We model the level of signal contamination, discuss proposed mitigation schemes, and present instrument requirements to inform the design of SO and future CMB projects.
