Cathode priming of a relativistic magnetron

Abstract

A cathode priming technique of a relativistic magnetron is analyzed via a three-dimensional particle-in-cell simulation. By imposing a threefold azimuthal variation on the emitting cathode of a six-cavity relativistic magnetron, the electrons are prebunched at birth. This leads to fast startup of the pi mode with three electron spokes. Suppression of unwanted modes during startup is observed in the simulation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70492/2/APPLAB-85-26-6332-1.pd
