3 October 1997 Diode plasma effects on the microwave pulse length from relativistic magnetrons
Author Affiliations +
A model to account for the shortening of the relativistic magnetron microwave pulse length based on radial cathode plasma motion is put forth and corroborated with measurements. If the dense, conducting, cathode plasma (and not the cathode itself) sets the diode electrostatic and microwave boundary conditions, its motion changes the magnetron resonance condition. Time varying microwave power envelopes and frequencies are both expected and observed. Based on the time scales, the main plasma ion constituent is inferred to be hydrogen and its source is likely adsorbed water. Results of an experiment to defeat the pulse- shortening mechanism are presented and compared to the results from similar experiments conducted by other researchers.
