Abstract
A DC operated printhead emits electrons by field emission at each crossing of first and second electrodes. Plural small electrode sets consisting of a cathode emitting cone and an anode aperture form a gap which less than the electron mean free path in an ambient atmosphere, and the sets are preferably closely spaced to form a substantially collimated beam. A third electrode preferably accelerates and cleans up the beam. Different gases may be used to increase emission or transport efficiency, and enhance electrode lifetime.
