A dynamic electron emitter includes a cold cathode in a cathode chamber emitting electrons in a focussed beam at and through a small orifice into a receiving chamber containing an anode and which may be the chamber of an ion gun. The orifice size is critical in that it must be small enough to ensure a higher pressure in the cathode than in the receiving chamber yet large enough to pass therethrough a sufficiently large flux of electrons to accomplish the intended purpose of the electron stream.
