Degree Angular Scale Interferometer
DASI is a 13-element interferometer designed to measure temperature and polarization anisotropy of the Cosmic Microwave Background (CMB) Radiation over a large range of scales with high sensitivity. The instrument uses cooled HEMT amplifiers running between 26-36GHz, in ten 1 GHz channels and operates from the NSF Amundsen-Scott South Pole station. Funding for DASI comes from the NSF Office of Polar Programs initially via the Center for Astrophysical Research in Antarctica, CARA, a NSF Science and Technology Center, and currently through a grant directly from the Office of Polar Programs. The Center for Cosmological Physics (CfCP) provides additional support at Chicago.
