Abstract

We have developed a system for making measurements of spatial fluctuations in the Cosmic Microwave Background Radiation at 3 mm wavelength, on an angular scale of.5 to 5 degrees. The system includes a telescope with a Gaussian beam with full width at half maximum (FWHM) of 20 to 50 arc-minutes, a Superconductor-Insulator-Superconductor (SIS) coherent receiver operating at 90 GHz, and for balloon flights, a pointing system capable of 1 arc-minute RMS stabilization. We report on results from the first flight of the stabilized platform, as well as results from ground based measurements made from the South Pole station in December, 1988.
