    Abstract: A method of fabricating a microchannel plate includes defining a plurality of pores extending from a top surface of a substrate to a bottom surface of the substrate where the plurality of pores has a resistive material on an outer surface that forms a first emissive layer. A second emissive layer is formed over the first emissive layer. The second emissive layer is chosen to achieve at least one of an increase in secondary electron emission efficiency and a decrease in gain degradation as a function of time. A top electrode is formed on the top surface of the substrate and a bottom electrode is formed on the bottom surface of the substrate.

    Abstract: An image intensifying device includes a lens that is positioned at a light input that forms an image of a scene. The image intensifying device also includes an image intensifier tube that includes a photocathode that is positioned to receive the image formed by the lens. The photocathode generates photoelectrons in response to the light image of the scene. The image intensifier tube also includes a microchannel plate having an input surface comprising the photocathode. The microchannel plate receives the photoelectrons generated by the photocathode and generating secondary electrons. An electron detector receives the secondary electrons generated by the microchannel plate and generates an intensified image of the scene.

    Abstract: A microchannel amplifier includes an insulating substrate that defines at least one microchannel pore through the substrate from an input surface to an output surface. A conductive layer is formed on an outer surface of the at least one microchannel pore that has a non-uniform resistance as a function of distance through the at least one microchannel pore. The non-uniform resistance is selected to simulate saturation by reducing gain as a function of input current and bias voltage compared with uniform resistance. A first and second electrode is deposited on a respective one of the input and the output surfaces of the insulating substrate. The microchannel amplifier amplifying emissions propagating through the at least one microchannel pore when the first and second electrodes are biased.
