A search for polarization of the Cosmic Microwave Background at 33 GHz - Preliminary observations of the South Celestial Pole region

We report the first results of a program of 33 GHz polarimetric observations of the CMB, at angular scales of 7 and 14 degrees. The observations were made from the Italian base at Terra Nova Bay. We were able to set upper limits of less than 10(-4) on the degree of linear polarization of the CMB. We...

Description
Summary:We report the first results of a program of 33 GHz polarimetric observations of the CMB, at angular scales of 7 and 14 degrees. The observations were made from the Italian base at Terra Nova Bay. We were able to set upper limits of less than 10(-4) on the degree of linear polarization of the CMB. We describe plans to reduce the receiver noise, and to move the experiment to Dome C in Austral Summer 1998-99.
