3-D modeling of electron beam devices

Summary form only given. New advanced analysis codes are allowing design and development of a new generation of electron devices. The ability to simulate 3D structures and electron beam propagation in non-symmetric, electromagnetic fields provide design capabilities that were not available a few years ago. In the last few years, Calabazas Creek Research, Inc. (CCR) has used its 3D analysis code Beam Optics Analyzer (BOA) to simulate single and doubly convergent multiple beam klystrons, gridded cathodes, advanced lighting fixtures, periodic permanent magnet (PPM) focused multiple beam klystrons, bombarders for electron beam of cathodes, the effect of cathode tilt and offset on beam propagation in a single beam electron gun. Other BOA users are developing advanced x-ray devices, including the effects of secondary electron emission in non-symmetric fields.
