DESIGN OF A MOLECULAR AMPLIFIER GROUP,

Abstract

This report discusses the results of a study program to design, develop, and fabricate a traveling-wave maser system having a magnetic field that is obtained from a superconducting magnet. The maser utilizes a ruby-loaded comb structure operating at a bath temperature of 4.2 K. It is tunable from 2195 to 2320 Mc, hav ing stable net gains in excess of 30 db with an instantaneous bandwidth of about 17 Mc. Gain stability is accomplished egrally including yttrium iron garnet isolator disks. Effective maser noise temperature (Te) measurements, maddawith a hot and cold load noise generator, yielded Te is approximately equal to 7.5 K. (Author)
