Abstract

Electron source device for an electronic gun, comprising a perforated control electrode in the form of a ferrule, in which a cylindrical cathode having a emitting end surface is secured by means of a plurality of thin support members, a cylinder of support, an insulating body in the form of a cylindrical ring, and an annular metallic body that is secured to the control electrode characterized in that the outer cylindrical face of the insulating body is connected to the annular metal body and its internal cylindrical face is secured to the cylinder of support by means of a substance fused therewith, the ends of the support cylinder protruding with respect to the insulating body and the cathode support members being secured, on the one hand, to the cathode holder and, on the other hand, to a flange provided on the end of the support cylinder adjacent to the emitting surface of the cathode, being secured or the annular metallic body to a plurality of depressed tongues in the cylindrical wall of the control electrode.
