西蒙斯天文台(SO)是一套宇宙微波背景仪器，将部署在智利的阿塔卡马沙漠。关键的科学目标包括对宇宙膨胀设定新的限制，用引力透镜测量大尺度结构，以及限制中微子质量。要实现这些科学目标，SO需要高灵敏度和改进的校准技术。在这篇文章中，我们重点介绍了一些最重要的仪器校准，包括光谱响应、增益稳定性和偏振角校准。我们介绍了他们对SO的要求，以及可以用来达到这些要求的实验技术。
The Simons Observatory (SO) is a set of cosmic microwave background instruments that will be deployed in the Atacama Desert in Chile. The key science goals include setting new constraints on cosmic inflation, measuring large scale structure with gravitational lensing, and constraining neutrino masses. Meeting these science goals with SO requires high sensitivity and improved calibration techniques. In this paper, we highlight a few of the most important instrument calibrations, including spectral response, gain stability, and polarization angle calibrations. We present their requirements for SO and experimental techniques that can be employed to reach those requirements.
