Church award abstractThis award supports a feasibility study of a Bolometric Array Receiver for Measurements of Polarization of the Cosmic Microwave Background Radiation. This instrument would search for polarization at millimeter wavelengths using a bolometer array that will simultaneously observe 40 pixels on the sky in two orthogonal directions of linear polarization. The receiver would be mounted on a 1.5m telescope sited at Mauna Kea, Hawaii, a location that combines superb observing conditions with a cheap, convenient location that has good existing support facilities. The instrument would be optimized to observe at frequencies of 100 to 220 GHz to allow the tiny polarized signal to be distinguished from astrophysical foregrounds. This instrument would allow a precise measurement of the power spectrum of polarization modes over an l-range of 50 to 1000. ***

教会奖摘要这个奖项支持一个辐射热阵列接收器的可行性研究，用于测量宇宙微波背景辐射的偏振。 该仪器将使用测辐射热计阵列搜索毫米波长的偏振，该测辐射热计阵列将同时观察天空中两个正交方向的线性偏振的40个像素。 接收器将安装在位于夏威夷莫纳克亚山的1.5米望远镜上，这个地点既有极好的观测条件，又有便宜、方便的地点，现有的支持设施也很好。 该仪器将进行优化，以在100至220 GHz的频率进行观测，以便将微小的偏振信号与天体物理前景区分开来。 该仪器将允许在50至1000的l范围内精确测量偏振模式的功率谱。 ***
