Abstract

We have developed and flown a balloon-borne liquid-heliumcooled spectrometer to measure the cosmic background radiation in the 3 -18-cm/sup -1/ region. It features a cooled horn antenna, a polarizing Michelson interferometer, and a germanium bolometer. These design features and the performance of the instrument are discussed.

Abstract

Mountaintop observations were made at 1 per cent spectral resolution of atmospheric and sky emission in an attempt to determine the spectral features of submillimeter background radiation. No emission features were found that could be related to the diffuse isotropic flux reported from rocket and balloon experiments.
