Abstract of the Disclosure The novel electron gun comprises a plurality of cathode assemblies and at least two spaced successive electrodes having aligned apertures 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. The ceramic member has a first major surface and an oppositely disposed second major surface, with a metallized pattern 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. A transition member is attached to the metallized pattern on the first major surface. The transition member includes a substantially flat portion attached to the metallized pattern on the first surface, and two upright portions substantially perpendicular to the flat portion and substantially parallel to each other. One of the electrodes is disposed between the upright portions and attached thereto so that the electrode is longitudinally spaced from the other electrode.
