我们描述了QUaD实验，一个毫米波长偏振计，旨在观察宇宙微波背景（CMB）从南极的一个网站。该实验包括一个2.64米卡塞格伦望远镜，配备了一个低温冷却的接收器，其中包含62个偏振敏感测辐射热计阵列。焦平面包含两个不同频带的像素，100 GHz和150 GHz，角分辨率分别为5′和3.′5。高角度分辨率允许在宽范围尺度上观察CMB温度和偏振各向异性。该仪器于2005年初开始运行，并在连续三个南极冬季观测期间收集科学数据。
We describe the QUaD experiment, a millimeter-wavelength polarimeter designed to observe the cosmic microwave background (CMB) from a site at the South Pole. The experiment comprises a 2.64 m Cassegrain telescope equipped with a cryogenically cooled receiver containing an array of 62 polarization-sensitive bolometers. The focal plane contains pixels at two different frequency bands, 100 GHz and 150 GHz, with angular resolutions of 5′ and 3.′5, respectively. The high angular resolution allows observation of CMB temperature and polarization anisotropies over a wide range of scales. The instrument commenced operation in early 2005 and collected science data during three successive Austral winter seasons of observation.
