Paper Abstract

The design and operation of a gas millimeter-wave spectrometer based on a tunable generator orotron are presented. The absorption cell occupies a part of the high quality (Q approximately equals 104) orotron Fabry-Perot cavity. The limit of sensitivity (gamma) min approximately equals (3- 5)X 10-10 cm-1 has been achieved with source frequency modulation at the output band of a receiver of 1 Hz. The narrow spectral width of the orotron radiation (10 - 15 kHz without locking) provides the Doppler resolution of spectral lines.
