Abstract: A method and apparatus for preventing oscillations in high-current electron guns. Spurious oscillations frequently occur as a result of interaction of the electron stream with the fields of resonant modes of the gun structure. The resonant impedances of the modes are lowered by damping with lossy dielectric or resistive materials which are suited to the high temperature and vacuum environment of electron guns. The lossy materials are located in places shielded from high electric fields applied to the gun. Lossy dielectric materials which are D.C. insulators may be used as insulating supports for gun electrodes.

Abstract: In an electron gun assembly for use in multi-beam type cathode ray tube of the type including a plurality of grid structures in which the groups of the grid electrodes of respective guns are formed as integral units, the grid electrodes of each group are impressed with the same potential and perform the same function, and wherein an electron lens is formed between adjacent grid structures, an assembly of a plate member or a superposed plate member is secured to one or both of the opposing ends of the grid structures. Each plate member is provided with a plurality of openings which are arranged to correspond to a predetermined arrangement of a plurality of electron guns, and each opening is surrounded by an axial edge. The edges function to prevent electric fields formed by the openings from being affected by the side walls of the grid structures opposing the openings thereby decreasing the astigmatism of the main electron lens.

Abstract: An electron source is provided by thermionic filaments in the form of elongated strips or wires, such filaments being mounted within a casing. A deflector electrode is formed on a wall of the casing behind the filaments and director electrodes placed forward of the filaments in the direction in which the electron flow is desired. The various electrodes are positioned relative to the filaments and have potentials applied thereto such that uniform distribution of electrons is provided over a predetermined area over which electron flow is desired. The filaments are resiliently supported in the casing so that they are appropriately tensioned to avoid sag when they are heated, and are able to withstand shock and vibration.

Abstract: Apparatus and method are disclosed for launching a high energy beam of charged particles along an axis into a substantially long path region from an exit aperture, in a manner such that the beam remains confined without application of external focusing fields in the region. The apparatus comprises a cathode, which is a source of electrons to compose the beam, and electrode means for producing an axial accelerating electric field to accelerate electrons in the beam to a relativistic velocity in an accelerating space. At relativistic velocity, the beam itself produces a solenoid-shaped magnetic field which undesirably tends to converge the beam when ionized gas molecules neutralize the space charge in the beam. An external magnet means for producing an axial magnetic field in the accelerating space and a radial magnetic field at the exit aperture, imparts a cyclotron angular momentum to the electrons. The cyclotron angular momentum provides a force to the electrons to substantially cancel the force of the self-magnetic field. Once the beam leaves the accelerating and cyclotron motion inducing space, it remains confined to a desired range of cross section. Such beams may be used for heating plasmas, or in high power microwave oscillators and amplifiers.
