Polarization Observations of Large Angular Regions

Phase Testing the POLAR experiment

POLAR is a Cosmic Microwave Background (CMB) experiment designed to look for polarization in the CMB at large angular scales. It is a single-pixel, correlation polarimeter that operated in the Ka frequency band (26-36 GHz). It collected approximately 750 hours of data from its observation site in Pine Bluff, Wisconsin, from March 10 through May 29, 2000. It has since been decommissioned, and its radiometer has been integrated into the COMPASS Telescope. Analysis of the single season of data set an upper limit of 10 µK on both E- and B- mode polarization on angular scales greater than 7°.
