Nonlinear guiding-center electron flow equilibria in crossed field devices

Summary form only given, as follows. As a research initiative to identify the origin of and develop methods to control phase noise in crossed-field amplifiers, a guiding-center theory of nonlinear equilibrium electron flow in a crossed-field device is presented. Unlike most of well-known equilibrium theories, the effect of the periodic anode structure is treated rigorously. Several examples of nonlinear guiding-center electron flow equilibria are discussed for configurations consisting of an inner cathode cylinder and an outer periodically corrugated anode. MAGIC simulations are performed to investigate the accessibility of such equilibria.
