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{sup 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 dependent scaling, based on the coupling of electrostatic energy from the ferroelectric to the gun, is presented. {copyright} {ital 1999 American Institute of Physics.}
