ABSTRACT:
The present invention provides an emitter structure of a field emission electron gun. The emitter structure comprises an emitter being electrically conductive and being pointed at the top, wherein the top of the emitter has the highest resistance of every other part, so that the top of the emitter has the highest heat energy of every other part when the emitter emits electrons.
