Abstract: The coil end-turn segments of a generator exciter rotor are retained using an end-turn retention assembly that includes an inner band and an outer band. The inner band is located around at least a portion of each of the end-turn segments and has two ends. The outer peripheral surface of the inner band is tapered such that the thickness of the inner band varies between its ends. The outer band is located around the inner band and also has two ends. The inner peripheral surface of the outer band is tapered in a fashion that is reverse to that of the inner band outer surface, and such that the outer band thickness varies between its ends. By forming oppositely configured tapers in the inner and outer bands, the outer bands will remain in place and not migrate axially away from the lamination core during exciter rotor rotation.

Abstract: A hydrogen storage material having improved hydrogen absorbtion and desorption kinetics is provided by adding graphite to a complex hydride such as a metal-doped alanate, i.e., NaAlH4. The incorporation of graphite into the complex hydride significantly enhances the rate of hydrogen absorbtion and desorption and lowers the desorption temperature needed to release stored hydrogen.

Abstract: An optical system comprising a first array of individual beam shaping elements and a second array of beam shaping elements placed between a light source, e.g., a linear array of individual laser diodes and a reshaped beam receiver, e.g., an optical fiber cable. The inhomogeneous beams emitted from the laser diodes are passed in sequence through the first and second stages so that the first stage reshaped the cross section of the beam, e.g., in the fast-axis direction and the second stage reshapes the cross section of the beam, e.g., in the slow-axis direction. As a result, the output beams of the system may have a cross section reshaped to any desired configuration, e.g., suitable for inputting into the optical fiber cable and having divergences individually adjusted in mutually perpendicular directions.

Abstract: A multiple-cell plasma source consists of a pair of perforated plate-like cathodes and a perforated plate-like anode between the both cathode plates. Perforations in all three plates are coaxial and form a plurality of cells in which a Penning discharge plasma is generated due to the passage of axial components of the magnetic field through the individual cells. Since in all cells the plasma flow components are generated and work independently, there are no limitations for an increase in the surface area of the upper cathode plate, which has plasma emitting holes, so that the plasma source can treat objects of a large surface area. The plasma source of the invention has various means for controlling and adjusting the plasma pattern, distribution, parameters, and shape.

Abstract: A cold-cathode type ion-beam source with a closed-loop ion-emitting slit and electrons drifting in crosses electric and magnetic fields is characterized by the absence of a metal anode which is replaced by a pair of positively charged bodies, such as concentric rings of a conductive material which are located inside a hollow housing of the ion source and are connected to a source of a positive potential. The ion-emitting slit is located between these rings in an upstream position in the direction of propagation of the ion beam. Replacement of a metallic anode with an anodic plasma, i.e., with a “virtual anode”, which is formed by a Penning-type discharge, descreases contamination of the ion beam by products of erosion of a metallic anode and increases the ion beam current, which results in more effective ionization of the workout gas.

Abstract: The invention provides a multiple-cell ion-beam source in which magnetic poles of all adjacent cells have alternating polarities, i.e., the cells arranged in a single row from the center to the periphery of the cathode plate have polarities in the order of N-S-N-S-N . . . , etc. As a result, the direction of magnetic lines of forces in the aforementioned rows alternates, and therefore the magnetic flux is not accumulated towards the center. This means that the source of such a construction does not have dimensional limitations and ensures uniform distribution of the ion-beam current density over the entire surface of the object. Intensity of the magnetic field for each individual cell can be controlled individually. This allows adjustment in the distribution of the ion-beam current density over the surface of the object.

Abstract: The invention provides a sputtering system which consists of an ion beam and a target of a sputterable material. A distinguishing feature of the system of the invention is that the sputtering target forms a guide channel for an ion beam and sputtered particles, so that a portion of the ions collides with the walls of the target inside a closed volume of the target and forms neutral sputterable particles impinging the object. The other part of the ions goes directly to the object and participates in an ion-assisted overcoating. Thus, the special form of the target improves efficiency of sputtering, prevents scattering and the loss of the sputterable material. The system can be realized in various embodiments. One of the embodiments provides a multiple-cell system in which each cell has an individual ion-emitting slit formed by the end of a cathode rod of one cathode plate and the opening in the second cathode plate.

Abstract: A multiple-beam ion-beam assembly consisting of two or more concentrically arranged ring-shaped ion-beam sources having ion-beam slits that emit a plurality of ion beams which overlap on the surface being treated and thus ensure uniformity in distribution of ion currents on the treated surface. Since the ion-beam assembly consists of a plurality of individual source, uniform treatment can be performed on a large surface area. Several embodiments of the invention cover the systems with individual sources adjustable with respect to one another, with an oblique angle of incidence of beams emitted from individual source, and with combination of oblique angles and adjustable sources.

Abstract: A combined ion-source and sputtering magnetron apparatus of the invention comprises a vacuum working chamber that contains a sputtering magnetron, an object to be treated fixed inside the housing of the chamber, and an ion-beam source installed within the working chamber between the object and the sputtering magnetron. In a preferred embodiment, the ion source is a cold-cathode ion source with a closed loop ion-emitting slit and drift of electrons in crossed electric and magnetic fields. The ion source emits the ion beam in the radial inward or outward direction onto the surface of the magnetron target at an oblique angle to the target surface. The bombardment of the target surface with the ion beam generates a large amount of sputtered particles. In addition, the ion bombardment forms a large amount of secondary electrons which are accelerated in the direction away from the target and are held in the crossed electric and magnetic fields of the magnetron target.
