Electron beam accelerator

摘要

The invention relates to an electron accelerator comprising a vacuum chamber having an electron beam exit window, the vacuum chamber being formed within an elongate member; an electron generator positioned within the vacuum chamber for generating electrons; a high voltage connector positioned within the elongate member for supplying power to the electron accelerator; a high voltage insulator separating the vacuum chamber from the high voltage connector; and a housing surrounding the electron generator, the housing having at least one opening formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window; wherein the vacuum chamber is sealed.
