摘要:
A universal cold-cathode type ion source with closed-loop electron drifting and with ion-beam propagation direction perpendicular to the plane of electron drifting is intended for uniformly treating stationary or moveable objects. Treatment procedures include cleaning, activation, polishing, thin-film coating, or etching. The ion source of the invention allows for adjusting beam parameters and configurations and has an adjustable dimensions of the ionization space between the anode and the cathode. In a preferred embodiment, the adjustment is carried out by moving the anode with respect to the cathode. The moveable anode is shifted in the direction of propagation of the ion beam or in the opposite direction, whereby the tubular ion beam is either converged or diverged. As a result, it becomes possible to adjust the surface area being treated and characteristics of the ion beam such as average energy of ions in the beam and composition of the beam, in case of a multiple-component working medium.

A method and apparatus for elimination of speckle pattern in optical system by reducing coherence. The invention is based on the use of a rotating microlens array having a rotational speed chosen with reference to laser parameter. For a continuous laser this relationship consists in that the exposure time is sufficient for overlapping at least 10.sup.4 spot sizes of the speckle. For a pulse laser, the laser pulse time should be sufficient for shifting the speckle spot at least by the magnitude of its diameter. Several embodiments with modified coherence reduction units are available. One modified embodiment describes a rotating inclined plate which enhances coherence reduction by scanning the over the surface of the diffuser. Another embodiment describes the use of an optical conical rod with total internal reflection for creation of a plurality of non-coherent light sources.

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.

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.

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. Tubular or plate-like channeling targets are connected to the ion slits without any gaps in the form of a geometrical extensions of the individual ion-emitting slits. Another embodiment allows adjustment in the position of the rods with respect to the targets.

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.

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.
摘要:
The ion source of the invention emits ion beams radially inwardly or radially outwardly from the entire periphery of the closed-loop ion-emitting slit. In one embodiment, a tubular or oval-shaped hollow body, which also functions as a cathode, contains a similarly-shaped concentric anode spaced from the inner walls of the cathode at a distance required to form an ion-generating and accelerating space. The cathode has a continuous ion-emitting slit which is aligned with the position of the anode and is concentric thereto. A magnetic-field generation means is located inside the ring-shaped anode. When the ion source is energized by inducing an magnetic field, connecting the anode to a positive pole of the electric power supply unit, the cathode to a negative pole of the power supply unit, and supplying a working medium into the hollow housing, the electrons begin to drift in the annular space between the anode and cathode in the same direction in which the ions are emitted from the annular slit. By rearranging positions of magnet, anode, and cathode, it is possible to provide emission of ions in the inward or outward direction for treating outer or inner surfaces of tubular objects.
