Design of magnetron injection gun and collector for high average power 95 GHz gyro-amplifiers

Summary form only given, as follows. The electrical design of a magnetron injection gun and collector for high average power TE/sub 01/ gyro-amplifiers has recently been completed using the EGUN and DEMEOS codes. The gun employs an optimized double-anode geometry and a radical cathode cone angle of 50/spl deg/ to achieve superior beam optics that are relatively insensitive to electrode misalignments and field errors. Perpendicular velocity spread of 1.6% at an perpendicular to axial velocity ratio of 1.52 is obtained for a 6 A, 65 kV beam. The 1.28" diameter collector, which also serves as the output waveguide, has an average power density of <350 W/cm/sup 2/ for a 59 kW average power beam. Further details on the gun and collector, and results from the design sensitivity studies are presented and discussed at the conference.
