2016-2017 USAP Field Season
Science observation with BICEP3 CMB polarization experiment
Dr. Chao-Lin Kuo
Supporting Stations: South Pole Station
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is an experiment designed to measure the polarization of the cosmic microwave background (CMB) to unprecedented precision, and, in turn, answer crucial questions about the beginnings of the Universe. BICEP3 is the latest upgrade to the BICEP/Keck series of refractor experiments that study degree-scale B-mode polarization from inflation. Compared to BICEP2 and SPUD (Small Polarimeter Upgrade for DASI), BICEP3's aperture is twice as large, allowing for a much larger focal plane area. BICEP3 doubles the survey speed of SPUD and focuses the sensitivity at 100 GHz, a frequency that is much less affected by dust foregrounds. BICEP3 is a powerful instrument to test whether BICEP2's measured signal is indeed of cosmological origin.
Field Season Overview
The team will remove the receiver from the BICEP mount, warm it up and replace four detector tiles. They will then cool it down again and load it back onto the mount. After verifying its performance, they will spend the remainer of their time on station measuring the beam response of the detectors.
