Abstract: A cathode for an electron tube is described in which a plurality of coating strips of electron emissive material are distributed parallel with each other over the face of a base. Projecting means along opposite edges of each strip extend above the surface of the base and toward each other to form a gap for the passage of electrons. Also described are a method for making such a cathode, and a tool useful in performing the method of the invention.

Abstract: A shaped beam tube is described wherein the means for shaping the cross section of the beam include a pair of axially spaced electron opaque members, each having a set of apertures therein. Each aperture in one set corresponds to an aperture in the other set for producing a particular desired image. The opaque members are positioned with their corresponding apertures aligned on the path of the electron beam.
