Abstract
An electron gun having at least one arc-suppression resistor located in a zero electric field gradient area of the electron gun is described. In the electron gun, at least one cathode is provided for generating an electron beam. A plurality of electrodes are also provided for directing the beam along the beam path. The electrodes include at least one accelerating and focusing electrode which is a split member having two spaced apart sections. The electron gun also includes at least one arc-suppression resistor which interconnects the spaced apart sections of the split electrode and is located in a zero electric field gradient area of the split member.
