Summary

The design and performance of an instrument to measure cosmic microwave background anisotropy on angular scales from 10' to 30' is reported. The instrument utilizes a single-mode waveguide bolometer cooled by an adiabatic demagnetization refrigerator. This is the first time a 100 milliK bolometer has been used in a cosmic microwave background experiment. Observations were made using this radiometer from the South Pole during the 1991-1992 season and, with minor modifications, during the 1992-1993 season. The radiometer is used with a fully steerable altitude-azimuth Cassegrain telescope built for this observation, also described in the paper.
