Abstract
The properties of a cathode consisting of an internally coated hollow shell with an aperture have been measured for a variety of geometries. Electrons are emitted from the edge of the aperture at current densities as high as 30 amp/sq cm. The cathode is particularly adapted to producing hollow or odd-shaped electron beams.
