Multibeam electron gun having electrodes supported by a formed transition member

Abstract From the Canadian patent

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 …
