    摘要: An electron beam gun generates an electron beam directed at a target. The gun comprises electrodes for creating an electric field along the direction of beam travel and focusing coils for creating a magnetic field along the direction of beam travel. The electrodes include a plurality of members each having a beam-shaping aperture therein for passage of the beam substantially without interception of the electrons in the beam. The electrodes and focusing coils are disposed for accelerating electrons in the beam in non-parallel paths through the beam-shaping apertures and for converging the electrons in the beam in at least one cross-sectional dimension of the beam to minimize that dimension at the target.
