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.
