    Abstract: A method and apparatus for merging electrons and ions in a neutralizer region where both are of equal intensity and velocity and directing the beam at a target to be destroyed. The region for merging the beams comprises a plurality of circular electrodes formed in a convex overlapping configuration with circular apertures for receiving ions from a ion source. A separate set of accelerator-decelerator electrodes is positioned to merge the electron beam into the ions in the beam merging region. After the beam leaves the beam merging region it enters an elongated axial magentic field which compresses the beam as it is directed to an object to be destroyed.This device may be housed in a satellite capable of being transported into space and moved within a kill radius of an object. The beam density is determined by the choice of ion species and by merging the beams in a low interaction energy environment.

    Abstract: A method and apparatus for coating high temperature resistant, electrically-conductive, ceramic compounds, such as titanium carbides and diborides, onto an organic substrate, which may be an organic resin matrix composite. The apparatus basically comprises a vacuum arc plasma generator, a high-voltage insulated substrate holding table and a plasma channel. The plasma generator includes a vacuum chamber having a cylindrical cathode of the material to be deposited, surrounded by a ceramic insulator which is in turn surrounded by a metal trigger ring in contact with a trigger electrode. When a vacuum arc discharge is initiated, a plasma flows outwardly from the cathode through a hole in an adjacent anode and into a drift tube. The drift tube has a plurality of magnets around the tube exterior to push the plasma away from the tube, maintain a uniform plasma density and guide the plasma towards a substrate on a movable high voltage insulated substrate support. The cathode material is nearly 100% ionized, giving the ions impinging on the organic substrate sufficient kinetic energy to react with and adhere tightly to the target substrate without additional heating. The amount of kinetic energy is controllable to provide the selected degree of substrate surface ion mixing with the coating elements.

    Abstract: A method and apparatus for modifying the inner surface of a tube by ion surface modification techniques, such as ion implantation, ion mixing and ion beam assisted coating. The apparatus includes a plasma source, preferably a vacuum arc, a first magnet for guiding the plasma into a drift tube. A second magnet is spaced from the first magnet and has a current running opposite to the first magnet. A radial extractor surrounds the area between the magnets, which form a cusp therebetween. The plasma follows the field lines, exiting the drift tube to the extractor, where the ions are removed and accelerated outwardly in a radial direction. With the entire apparatus placed in a tube, the ions will impact the inner wall of the tube. The resulting ion implantation advantageously modifies the surface, typically increasing wear and erosion resistance, improving corrosion resistance, increasing fatigue life, etc. The apparatus may be used to coat the tube interior with the cathode material by operating the extractor at a lower voltage or omitting the extractor. The apparatus may be inserted in tubes and moved along the tube to treat the walls of very long tubes.

    Abstract: A cathodic arc metal deposition apparatus that prevents the deposition of metal droplets with the metal ions being deposited. The cathode has an annular configuration. An annular solenoidal magnet is positioned adjacent to the cathode with their central openings in alignment. The opening diameters and spacings of the cathode and magnet is such that no line of sight exists between the cathode and a target to be coated. Preferably, the arc is initiated between the cathode and an annular anode located around the cathode, separated from the cathode by an insulating layer. The arc is initiated by a high voltage pulse formed between a trigger electrode ring within the cathode opening and the cathode. In an alternative embodiment, a plurality of individual cathodes are positioned in a circle in place of the single ring electrode. The anode may surround the set of cathodes, or may be a screen between the cathodes and the magnet. A multi-screen extractor is preferably provided to direct ions toward the target.
