Abstract : The optimization of crossedfield systems is studied from the viewpoint of power output and efficiency by using variablepitch slowwave circuits and depressed collectors. The nonlinear equations describing energy exchange between an electron beam and an rf wave are derived, valid for variable phase velocity and variable electron beam velocity. These equations are simplified with the hardkernelbunch assumption which makes it possible to obtain closedform solutions for the conversion of potential energy alone, the conversion of kinetic energy alone, and the combined conversion of potential and kinetic energy into rf energy. The phasevelocity variations hand the concurrent change in electron beam velocity which are required to maximize power output are derived from the theory and presented for various parameters.
