Microchannel plate with coated output electrode to reduce spurious discharges

摘要

A microchannel plate (MCP) apparatus and method in which the output metalization layer or electrode is covered with a thin coating to reduce the number of spurious electron emissions striking the phosphor screen or other collection anode in an image intensifier. Microchannel plates manufactured in this way have the beneficial effect of improving yield in the manufacture of night vision devices.
