Crossed-Field, High Energy Microwave Source Experiments and Theory
Abstract
Relativistic magnetron experiments have successfully been accomplished utilizing the MELBA accelerator at parameters of -300 to -400 kV, 1-10 kA and pulselengths of -0.5 microseconds. A major accomplishment has been the installation of a ceramic insulator stack, which has improved the base vacuum by a factor of 10 from 10-0 Torr scale to the 10-1 Torr scale. The Titan-Pulse Sciences magnetron is a 6-vane device operating at about 1 GHz. Microwave power has been extracted from two-opposing-cavities of this magnetron. Assuming equal output power in both arms, peak, extracted microwave power between 120 MW and 400 MW has been achieved. Microwave pulse shortening is observed with typical pulselengths in the range between 10 ns and 100 ns. Time-frequency analysis has been utilized for mode identification, indicating both the pi-mode and the 213 -pi mode.
