Abstract: An electron gun (10) comprises, as in prior guns, a plurality of cathode assemblies (16) and at least two spaced successive electrodes (18,20) having aligned apertures (60, 64) therethrough for passage of a plurality of electron beams. The cathode assemblies and the electrodes are individually held in position from a common ceramic member (50) The ceramic member has a first major surface (52) and an oppositely disposed second major surface (54), with a metallized pattern (56a, 56b; 56c) formed on at least a portion of each major surface. The electrodes are attached to the first major surface, and the cathode assemblies are attached to the second major surface. Unlike prior guns, a first transition member (74/78) is attached to the metallized pattern (65a, 56b) on the first major surface. At least one of the electrodes is attached to the first transition member. A second transition member (68, 94) may also be disposed on the second major surface for the attachment of the cathode assemblies.
