Abstract :
Electron trajectories in a 4 + 12 RF gun were calculated by a 2-D simulation code newly developed with full Maxwellian equations with space charge effects taken into account self-consistently to evaluate RF gun performance characteristics, in particular, the effects due to backstreaming electrons. The energy spectra, and current profile of the backstreaming electrons were calculated to show appreciable concentration to the limited area of the cathode, and also that the high energy backstreaming electrons are mainly originated in the 4th cavity of the RF gun.
