ABSTRACT:
A method of processing elements of an electron gun assembly for electron beam tubes and the like, wherein the electron gun assembly in completed form includes a cathode and at least a control grid and first anode rigidly assembled together, the control grid and first anode each comprising a substrate having a substrate aperture therethrough and a flat face substantially perpendicular to the electron beam to be formed covered with a thin layer of metal at least adjacent the substrate aperture having a shaped beam-controlling aperture therethrough. The control grid and first anode substrates are processed to preform the substrate apertures therein, the flat metal layers are formed on a flat face of the substrates spanning the substrate apertures, these substrates and the cathode are mounted as a rigid skeleton subassembly on a laser bench, and a laser beam is directed onto portions of the metal layer spanning the substrate apertures to form the beam control apertures therein.
