ABSTRACT:
An electron gun comprises at least one cathode for generating an electron beam along a beam path and a plurality of electrodes serially disposed along the beam path. The electrodes include at least one accelerating and focusing electrode having two spaced-apart electrode sections axially separated along a plane substantially perpendicular to the beam path. An arc-suppression resistor interconnects the spaced-apart electrode sections of the electrode. The interconnected electrode sections normally operate at substantially the same voltage. The arc-suppression resistor acts in the event of an arc to limit the arc current and prevent damaging cascading arcs.
