ABSTRACT:
An electron accelerator for generating an electron beam includes a vacuum chamber having an outer perimeter and an electron beam exit window. The exit window has a central region and a first end region. An electron generator is positioned within the vacuum chamber for generating electrons. The electron generator and the vacuum chamber are shaped and positioned relative to each other to accelerate the electrons in an electron beam out through the exit window. The electrons pass through the central region of the exit window substantially perpendicular to the exit window and through the first end region of the exit window angled outwardly relative to the exit window. At least a portion of the outwardly angled electrons are directed beyond the perimeter of the electron accelerator.
