Abstract

The sensitivity of a Stark-modulated waveguide microwave spectrometer can be significantly improved by using a traveling wave tube or solid state microwave amplifier prior to the crystal detection. In this paper the traveling wave tube is discussed. The increase in sensitivity results from the improved noise figure of the traveling wave tube relative to crystal video type detectors. Wide bandwidth traveling wave tube or solid state amplifiers are available so full waveguide bandwidths may be utilized. Rotational transitions for J equals 1 yields 0 lines of cyanogen bromide, BrCN, were measured with the traveling wave tube system and a standard video detector and the spectra are given here.
