  • Microchannel plates formed with deposition using non-reactive gas
    Patent number: 4945286
    Abstract: A method is provided for depositing a conducting electrode on the output face of a microchannel plate and into the output end of each channel. The electrode is vapor deposited by a method which ensures that the material impinges on the output face from random angles relative to the axis of each channel. A layer (10) of tapering thickness is formed down each channel. When used in an image intensifier tube, for example, the output beam of electrons from each channel is more collimated and the resolution of the tube is improved.
