ABSTRACT:
A microchannel plate includes a substrate defining a plurality of pores extending from a top surface of the substrate to a bottom surface of the substrate. The plurality of pores includes 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 positioned on the top surface of the substrate and a bottom electrode is positioned on the bottom surface of the substrate.
