BICEP3 is a 520mm aperture on-axis refracting telescope observing thepolarization of the cosmic microwave background (CMB) at 95GHz in search of theB-mode signal originating from inflationary gravitational waves. BICEP3's focalplane is populated with modularized tiles of antenna-coupled transition edgesensor (TES) bolometers. BICEP3 was deployed to the South Pole during 2014-15austral summer and has been operational since. During the 2016-17 australsummer, we implemented changes to optical elements that lead to better noiseperformance. We discuss this upgrade and show the performance of BICEP3 at itsfull mapping speed from the 2017 and 2018 observing seasons. BICEP3 achieves anorder-of-magnitude improvement in mapping speed compared to a Keck 95GHzreceiver. We demonstrate $6.6\mu K\sqrt{s}$ noise performance of the BICEP3receiver.

2017 upgrade and performance of BICEP3: a 95GHz refracting telescope for degree-scale CMB polarization
