Abstract

We describe the instrumentation, experiment design, and data reduction for the first season of observations with the Degree Angular Scale Interferometer (DASI), a compact microwave interferometer designed to measure anisotropy of the cosmic microwave background (CMB) on degree and subdegree scales (l ≃ 100-900). The telescope was deployed at the Amundsen-Scott South Pole Research Station during the 1999-2000 austral summer, and we conducted observations of the CMB throughout the following austral winter. In its first season of observations, DASI has mapped CMB fluctuations in 32 fields, each 3°.4 across, with high sensitivity.
