Abstract
Data is presented on the production of electron beams from a ferroelectric cathode at voltages of order 0.5 MV and current densities of order 100 A/cm (2). In comparison with data at lower voltages, the beam current scales as the three-halves-power of the voltage. An interpretation of the voltage dep endent scaling, based on the coupling of electrostatic energy from the ferr oelectric to the gun, is presented.
