    Abstract: Radial radio frequency (RF) electron guns and radial RF electron gun systems are provided that are capable of generating an electron beam that can propagate either radially inward, towards the axis of a cylinder, or radially outward from the axis. A beam source capable of generating a radially inwardly propagating electron beam, while perhaps not particularly useful as a source for a higher-energy accelerator, offers potential advantages for materials processing, as the geometry allows irradiation from all sides of an enclosed material flow with a single structure. Other potential applications include, but are not limited to, atmospheric plasma generation, radiation damage testing, and possibly, novel electron lens-type devices for hadron accelerators.

    Abstract: An electron beam tube for use in formation and recordation of electrostatic charge patterns has a face plate including a photoconductive layer and a conductive base which is transmissive to electron beams and is disposed intermediate the photoconductive layer and the tube electron beam emitter. Processes for forming electrostatic charge patterns in such face plate include the steps of placing an insulative charge-retaining layer in contact with the photoconductive layer, the insulative layer either being previously charged or being charged while in position on the photoconductive layer, and applying a voltage to the face plate and simultaneously irradiating the photoconductive layer with pattern-indicating electron beams. Electrostatic charge patterns thus-formed in the insulative layer may be developed in place or transferred and subsequently developed.

    Abstract: A display device in which a cathode ray tube envelope is utilized with a plurality of conductive elements extending from the interior surface of the faceplate of the cathode ray to the exterior surface of the cathode ray tube. A high resolution faceplate is provided by fabricating the faceplate in a manner such that the conductive elements are formed on a surface transverse to the inner and outer surfaces of the faceplate and this transverse surface is then formed into the faceplate to provide a vacuum type window.
