Abstract
An electron gun includes a cathode, a cavity, and an energy input. The cavity resonates at a particular frequency, and the cathode generates an electron beam along its longitudinal axis when driven by resonant electromagnetic radiation of the particular frequency. The energy input introduces electromagnetic radiation of the particular frequency into the cavity along the longitudinal axis of the cathode.
