Relativistic Magnetron Priming Experiments and Theory
Abstract
Microwave/RF priming experiments have been performed on the UM relativistic magnetron. The high power RF priming source (40 kV, non-relativistic magnetron) was obtained on-loan from the Air Force Research Lab. Microwave power output from the AFRL priming magnetron was input into one arm of the three-waveguide extraction system on the relativistic magnetron. The UM/Titan A6 relativistic magnetron was driven by MELBA-C; the ceramic insulator yields 10-8 Torr scale vacuum for quasi-hard-tube conditions. Microwave priming experiments showed mode-beating effects at power levels and frequency detuning consistent with Adler's equation. Effects of microwave priming on start-oscillation time and microwave pulselength were also characterized. Major breakthroughs in this research were the discovery and demonstration of two new magnetron priming techniques: magnetic priming and cathode priming. Magnetic priming was patented by UM (US patent No. 6,872,929).
