Abstract

The condition for geometrical similarity of trajectories given by Dryden has been modified to be relativistically correct, thus allowing the complete Dryden-Harker procedure to be used to design electrodes for relativistic electron streams of limited velocity spread. The magnetic field in the cathode region has been modelled by an analytic expression, to allow converging field to be simulated while similarity of the magnetic force is retained. Examples are given of the use of the revised method for design of high-voltage and external electron guns for gyrotrons.
