Abstract: An intense, steady state, low emittance electron beam generator is formed by operating a hollow cathode discharge plasma source at critical levels in combination with an extraction electrode and a target electrode that are operable to extract a beam of fast primary electrons from the plasma source through a negatively biased grid that is critically operated to repel bulk electrons toward the plasma source while allowing the fast primary electrons to move toward the target in the desired beam that can be successfully transported for relatively large distances, such as one or more meters away from the plasma source.

Abstract: A cold cathode electron gun utilizes a metallic torus for electrostatic focusing of an electron beam. A nonconductive tube is disposed within and along the axis of the torus. A conductive aerodynamic body electrically connected to the torus forms an annular venturi in the tube and includes a face which serves as a high field emitting surface. High molecular weight gas is introduced into a proximal end of the tube at a stagnation pressure sufficient to produce supersonic flow thereby causing a vacuous gas region adjacent the emitting surface. The torus and emitting surface are driven to a very high negative potential by a Tesla transformer or the like, producing high field emission into the vacuous region. The electric field of the torus produces, from the emitted electrons, an electron beam which issues from the tube into the atmosphere.

Abstract: A diode pulser is described which comprises a diode and an inductor connected in series, the impedance of the diode being controllable to suddenly increase the impedance to produce a high voltage pulse across the diode. The diode includes concentric electrodes forming a gap between them across which electrons move. To increase the impedance, a magnetic field is suddenly applied parallel to the electrode surfaces, to bend the electron paths so as to require a much higher voltage to move the electrons across the gap, the inductor creating such voltage to maintain the current flow for a brief time. The diode pulser is useful as a rapid-acting switch, and as a source of high energy electrons that are useful to generate X-rays, microwaves, and for other purposes.

Abstract: A laser arrangement includes electron beam apparatus comprising a plurality of electrodes, each of which having an aperture therethrough. The apertures are aligned along the longitudinal axis of an envelope which surrounds them and contains gas. The electrodes are electrically connected such that, of an adjacent pair, one is at a lower potential than the other. An electron beam is produced between the first electrode and an adjacent electrode, and is accelerated along the axis through the apertures, the electron current increasing in magnitude. The electron beam produced is used to provide pumping powder to the gas contained within the envelope such that it acts as a laser amplifying medium.

Abstract: An ion plasma electron gun for the generation of electron beams which exhibits electron beam dose uniformity and which is capable of varying the dose received by a material to be irradiated. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid onto a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode, causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid in the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and uniform electron distribution which is subsantially the same as the ion distribution of the ion beam impinging upon the cathode. Means are provided for creating a pulse of secondary electrons by varying the period of time in which the secondary electrons are transmitted through the foil.

Abstract: In a mounting device for electrically heated, spirally wound wire cathodes in electron guns, two mounting posts joined together by an insulator are configured as sector-shaped sections of a hollow cylinder, and have each a circumferential groove on its end remote from the insulator. The surfaces defining the grooves are parts of common circular and cylindrical surfaces, and the mounting ends of the cathodes are of a configuration approximately complementary to that of the grooves in the mounting posts. The mounting ends therefore lie in a spring-biased and form-fitting manner in the circumferential grooves.
