The standard paraxial ray equation method  for the design of electrodes for an electrostatically focused gun is extended to include relativistic effects and the effects of the beam's azimuthal megnetic field. Solutions for parallel and converging beams are obtained and the predicted currents are compared against those measured on the High Brightness Test Stand .
