Abstract
A field effect electron emitter comprises a segmented emission surface and a control unit. The segmented emission surface has a plurality of field effect emitter needles and a number of segments, each segment having an activatable part emission surface, wherein the plurality of field effect emitter needles are distributed on the activatable part emission surfaces. The control unit is configured to activate various groups with at least one of the number of segments for a simultaneous electron emission from respective activatable part emission surfaces such that coherent and grouped part emission surfaces able to be activated in succession overlap in pairs by at least 25%.
