摘要: We describe the QUaD experiment, a millimeter-wavelength polarimeter designed to observe cosmic microwave background (CMB) from site at South Pole. The experiment comprises 2.64 m Cassegrain telescope equipped with cryogenically cooled receiver containing an array of 62 polarization-sensitive bolometers. focal plane contains pixels two different frequency bands, 100 GHz and 150 GHz, angular resolutions 5' 35, respectively. high resolution allows observation CMB temperature polarization anisotropies over wide range scales. instrument commenced operation in early 2005 collected science data during three successive Austral winter seasons observation.
