Abstract
An apparatus and method for reducing the incidence of electric field stress on portions of insulating structures within high voltage devices is disclosed. Each of the embodiments disclosed herein modifies the conductive properties of the insulating structure surface in a non-uniform manner such that the distribution of voltage potential along the surface thereof is more fully equalized during operation of the high voltage device. This, in turn, reduces the per unit stress on the insulating structure caused by the electric field of the high voltage device. Through embodiments of the present invention are preferably directed to utilization in x-ray tube devices, a variety of high voltage devices may benefit from application of the disclosed matter.
