ABSTRACT:
By using a large area cathode, an electron source can be made that can irradiate a large area more uniformly and more efficiently than currently available devices. The electron emitter can be a carbon film cold cathode, a microtip or some other emitter. It can be patterned. The cathode can be assembled with electrodes for scanning the electron source.
