Abstract

The nonlinear aspects of the interaction between externally applied electrostatic oscillations and a one-dimensional electron-ion plasma is investigated by numerically integrating the Vlasov-Poisson system of equations. The forcing field is in the form of a broad symmetric k spectrum which simulates that used in low-frequency wave-heating experiments in tokamak plasmas. It is shown that, for realistic values of the plasma and field parameters, numerous nonlinear effects accompany the wave-plasma interaction, as, for example, the formation of density cavities by the action of ponderomotive forces, the acceleration of charged particles, and the nonlinear plasma heating. © 1999 The American Physical Society.
