Query: Experiment Design and First Season Observations with the Degree Angular
  Scale Interferometer   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 in
the Cosmic Microwave Background (CMB) on degree and sub-degree scales
(l=100--900). The telescope was deployed at the Amundsen-Scott South Pole
research station during the 1999--2000 austral summer and 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
deg across, with high sensitivity.
