ABSTRACT:
An electron gun having arc suppression means is described. In one of the preferred embodiments of the electron gun, at least one cathode is provided for generating an electron beam along a beam path. A plurality of electrodes are serially disposed along the beam path. The electrodes include at least one low voltage electrode and at least one high voltage electrode. A plurality of resistors interconnect selected ones of the electrodes. The interconnected electrodes normally operate at substantially the same voltage, and the resistors act as a voltage divider in the event of an arc and prevent damaging cascading arcs.
