A cathode support assembly includes an apertured ceramic member, an apertured spring washer, and a dual diameter eyelet having an outwardly crimped portion and a peened end portion exerting a force on the ceramic member and spring washer therebetween. In the fabrication process, the ceramic member and spring washer are telescoped over the eyelet and into contact with the crimped portion and the end of the eyelet is peened into contact therewith to exert a force thereon.
