Abstract
At least one emitter formed of an electron emissive material is positioned on a cathode assembly and is readily and reliably connected to at least one mounting member of the cathode assembly. The connections between the at least one emitter and an emitter support structure are formed directly between the at least one emitter and the emitter support structure by utilizing the at one mounting member on the emitter support structure that are positioned adjacent the at least one emitter and heated to secure the at least one emitter to the emitter support structure by welding the at least one mounting member to the at least one emitter and emitter support structure.
