Wave-particle power transfer in a steady-state driven system.

摘要

The general expression of the power transfer from a high-energy ion beam to a background electrostatic plasma wave is obtained as a function of an arbitrary wave amplitude. The injection ions are assumed to slow down through classical transport processes and form a weakly destabilizing distribution function. It is verified that phase space gradients produced by a finite amplitude wave enhances the power transfer significantly, as was also indicated in earlier work. 4 refs., 3 figs.
