Coherent Structures and Chaos Control in High-Power Microwave and Charged-Particle Beam Devices

Abstract

This report summarizes research results obtained under the auspices of Air Force Office of Scientific Research, Grant No. FA9550-06-1-0269. In particular, we conducted vigorous theoretical and computational investigations of coherent structures and chaos in a wide range of intense electron beam plasmas relevant to the development of high-power microwave and particle-beam devices for directed energy applications. The research accomplishments includes: a) development of a small-signal theory of magnetrons, b) discovery of vortex structures in relativistic magnetrons, c) discovery of adiabatic thermal equilibria in periodically focused electron beams, d) design of high-brightness circular beam systems, and e) development of elliptic beam theory for high-power microwave device applications.
