  • Method of making thin-film continuous dynodes for electron multiplication
    Patent number: 5726076
    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.

  • Method for fabrication of discrete dynode electron multipliers
    Patent number: 5618217
    Abstract: A method for manufacturing a discrete dynode electron multiplier includes employing micromachining and thin film techniques to produce tapered apertures in an etchable substrate, bonding the substrates together and activating the internal surfaces of the etched substrate using chemical vapor deposition or oxidizing and nitriding techniques.

  • Method for fabrication of microchannel electron multipliers
    Patent number: 5569355
    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.
