ABSTRACT:
Disclosed herein is an x-ray field emission apparatus, system and method, the apparatus having a hollow probe held at vacuum; a cathode enclosed within the probe, the cathode producing an electron stream when connected to a high negative potential; an anode enclosed within the probe and separated from the cathode by a gap, said the providing a target for the electron stream; and a shield assembly comprising a hollow shield electrode positioned within the probe and about the cathode.
