ABSTRACT:
The electron gun with a field emission type cathode includes a substrate, a plurality of groups of cathodes disposed on the substrate, each group having a conically shaped electron-emitter, and gate electrodes each associated with each group of the plurality of groups of cathodes for causing the conically shaped electron-emitter to emit electrons by field emission. A control voltage can be applied independently to each group of the plurality of groups of cathodes, and also to the gate electrodes.
