摘要：

Polarization results from the Cosmic Anisotropy Polarization MAPper ( CAPMAP) experiment are reported. These are based on 433 hr, after cuts, observing a 2 deg(2) patch around the north celestial pole with four 90 GHz correlation polarimeters coupled to optics defining 4 ' beams. The E- mode flat band- power anisotropy within l = 940 (+330)(-300) is measured as 66(-39)(+53) muK(2); the 95% confidence level upper limit for B- mode power within l = 1050(-520)(+590) is measured as 38 muK(2).
