Abstract:

A microchannel plate device utilizing a semiconducting bulk material is characterized by electron emissions of high output current density and efficiency. The channel passages in the plate device which are square in cross-section accommodates a larger open area ratio at the input and output plate surfaces. An extended range of high electron emission applications for the plate device is provided. Such applications may include a photocathode installation to which a modulation pulse input is applied under low voltages isolated from high post-accelerating voltages.
