Bicep/ Keck XV: The Bicep3 Cosmic Microwave Background Polarimeter and the First Three-year Data Set
We report on the design and performance of the Bicep3 instrument and its first three-year data set collected from 2016 to 2018. Bicep3 is a 52 cm aperture refracting telescope designed to observe the polarization of the cosmic microwave background (CMB) on degree angular scales at 95 GHz. It started...
