Anisotropy of the Cosmic Microwave Background Radiation on Large and Medium Angular Scales

摘要9316535 Meyer这个项目将导致开发一个望远镜，用于长时间的南极绕极气球飞行，以测量宇宙微波背景辐射（CMBR）的各向异性。 该仪器将安装在气球的上表面，以消除气球和电缆等连接结构散射到孔径中的辐射的干扰，预计系统误差将小于百万分之一开尔文。 CMBR将在150至630 GHz的五个频率和0.5至3度的角度范围内进行测量。 该仪器将在美国进行测试之前不会在南极洲飞行。 该项目将得到NASA的部分支持，并由NSF的极地项目办公室和天文科学部提供资金。 这项合作包括来自美国四所大学、美国宇航局戈达德太空飞行中心和丹麦太空研究所的调查人员。 ***

Abstract 9316535 Meyer This project will lead to the development, for flight on a long- duration Antarctic circum-polar balloon, of a telescope to measure the cosmic microwave background radiation (CMBR) anisotropy. The instrument will be mounted on the upper surface of the balloon in order to eliminate interference from radiation being scattered into the aperture by the balloon and connecting structures such as cables and it is expected that the systematic errors will be less than one millionth of a kelvin. The CMBR will be measured at five frequencies from 150 to 630 GHz and on angular scales from 0.5 to 3 degrees. The instrument will not be flown in Antarctica until after it has been tested in the U.S. The project will be partially supported by NASA and will be funded by the Office of Polar Programs and the Division of Astronomical Sciences at NSF. The collaboration includes investigators from four US universities, NASA Goddard Space Flight Center and the Danish Space Research Institute. ***
