A cusp electron gun for millimeter wave gyro-devices

Research output: Chapter in Book/Report/Conference proceedingConference contribution book


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 and the results are given.
