Magnetron having a transparent cathode and related methods of generating high power microwaves

摘要

A cathode for use in a magnetron may include a plurality of longitudinally oriented emitter regions disposed around a longitudinal axis of the cathode. Each emitter region can be configured to emit electrons and adjacent emitter regions can be separated from one another by openings. The emitter regions can be configured to promote simultaneous cathode priming, magnetic priming, and electrostatic priming.
