Microchannel plate having low ion feedback, method of its manufacture, and devices using such a microchannel plate

摘要

Microchannel plates are provided having an array of multiple channel electron multipliers for use in night vision devices, image intensifier tubes, photomultiplier tubes, and other such devices with improved gain, higher signal-to-noise ratio, and better resolution. The microchannel plates disclosed herein utilize a bulk-conductivity substrate material, and provide features for improving secondary electron-emissivity of the material.
