Model Equations

Model equations describing the nonlinear coupling between electrostatic ion-cyclotron and drift waves are derived, taking into account the action of the low-frequency ponderomotive force associated with the ion-cyclotron waves. It is found that this interaction is governed by a pair of equations, which can be used for studying the modulational instability of a constant amplitude ion-cyclotron wave as well as the dynamics of nonlinearly coupled ion-cyclotron and drift waves.

AbstractWe present a kinetic theory analysis of the electrostatic ion cyclotron (EIC) instability in a plasma containing positive ions, electrons, and negative ions that are much more massive than the positive ions. Conditions are investigated for exciting the fundamental and the higher harmonic EIC waves associated with each ion species. We find that as the concentration of heavy negative ions increases, the wave frequencies increase, the unstable spectrum in general shifts to longer perpendicular wavelengths, and the growth of higher harmonic EIC waves tends to increase within certain parameter ranges. Applications to possible laboratory plasmas are discussed.
