Abstract

A thermionic cusp electron gun has been designed, numerically optimized and experimentally measured and is presented. A 40 kV, 1.5 A annular axis-encircling electron beam has been simulated to generate a beam with low velocity and alpha spreads. The electron gun performance has been verified through experiments. Based on the measured results further improvement and optimization of the cusp gun for high frequency operation were carried out and the results will be presented.
