Abstract: A microchannel plate and method is disclosed. In a preferred embodiment the microchannel plate is a water of anisotropically etchable material having been subjected to a directionally applied flux of reactive particles against at least one face of the wafer in selected areas corresponding to microchannel locations. The flux removes material from the selected areas to produce microchannels in the wafer in accordance with the directionality of the applied flux.

Abstract: The invention is directed to continuous dynodes formed by thin-film processing techniques. According to one embodiment of the invention, a continuous dynode is formed by reacting a chemical vapor in the presence of a substrate at a temperature and pressure sufficient to result in chemical vapor deposition. In another embodiment, the layer is formed by liquid phase deposition and in another embodiment, the layer is formed by nitriding or oxidizing a substrate.

CPC classification number: H01J9/125 , H01J2201/32
Abstract: The present invention discloses a method for constructing a completely micromachined MCP that is activated with thin-film dynodes wherein the interchannel regions are first dry etched in the substrate, resulting in channel pillars. The etched portions of the substrate are then back filled and the channel pillars are thereafter removed to produce a micromachined perforated microchannel plate. The technique may be employed to produce an active element for an integrated image tube or photomultiplier tube.

Abstract: Optical fibers are produced with improved cross sectional circularity. In the course of the fabrication process, the tubular preform from which the fibers are drawn, is collapsed under positive internal pressure. This removes most cross sectional noncircularities that may have developed during fabrication of the preform, and also ensures the collapse of the preform to a structure with circular cross section.

Abstract: A single mode optical transmission line consisting of a core and a clad, both formed from essentially the same type of multicomponent glass, e.g. borosilicate, for use with electromagnetic energy having a wavelength between 0.5.mu.m and 2.0.mu.m. The core has a higher refractive index than the clad because the relative concentrations of the constituents of the glass composition are varied between core and clad, e.g., the ratio of SiO.sub.2 /B.sub.2 O.sub.3 concentrations is higher in the core than in the clad.
