    Abstract: An electron gun comprises a shell having distal and proximal ends, a cathode structure disposed within the shell and having an electron emitting surface, an anode physically coupled to the shell at the distal end and spaced a fixed distance from the emitting surface, and a plurality of leads adapted to apply a voltage to the cathode structure with respect to the anode sufficient to cause emission of the electrons from the emitting surface. The anode has an aperture for passage therethrough of the beam of electrons emitted by the emitting surface. A first insulator is disposed within the shell proximal to the cathode structure. The first insulator has plural apertures having respective sizes in relation to corresponding ones of the plurality of leads such that the plurality of leads pass therethrough without contacting the first insulator. The first insulator provides stand-off for the voltage between the anode and cathode. A second insulator is disposed with the shell proximal from the first insulator.
