Abstract : The purpose of the program is to develop improved maser techniques and apply them to a broad-band maser system. The breadboard maser system is in its final stages of fabrication and assembly. Details of the system are described and performance tests will begin shortly. Anamolous limiting effects reported earlier for the semiconductor limiter were found to be caused by relaxation effects in the material. Measurements of a final configuration are presented and a novel pulse modulator mode of operation for the device is described. The Gunn effect in semiconductors was investigated as a possible pump source for traveling-wave masers. An initial study indicates that this approach to a solid-state pump source may be worthwhile.
