Abstract
A low volume, lightweight, high voltage electron gun having an overall size and weight of approximately 50% the size and weight of a conventional electron gun of the same output. This is accomplished by interposing between the cathode and the walls of the housing of the electron gun a thin piece of dielectric material of preselected breakdown strength. The dielectric material is in direct contact with both the cathode and the housing of the electron gun, with the voltage stress between the walls of the housing and the cathode being such that it does not exceed the breakdown strength of the dielectric material.
