Abstract
Electron trajectories in a 4 + 1/2 RF gun were calculated by a 2-D sim ulation code newly developed with full Maxwellian equations with space charge effects taken into account self-consistently to evaluate RF gu n performance characteristics, in particular, the effects due to backs treaming electrons. The energy spectra, and current profile of the bac kstreaming electrons were calculated to show appreciable concentration to the limited area of the cathode, and also that the high energy bac kstreaming electrons are mainly originated in the 4th cavity of the RF gun.
