Abstract Text:
Radio frequency (RF) waves can provide heating, current and flow drive, as well as instability control, and others nonlinear phenomenon for steady state operations of fusion experiments. A RF particle simulation has been developed in this work to provide a first-principles tool for studying the RF nonlinear interactions with plasmas. In this model, ions are considered as fully kinetic particles using the Vlasov equation and electrons are treated as guiding centers using the drift kinetic equation with realistic electron-to-ion mass ratio. This model has been verified in the global gyrokinetic toroidal code (GTC) linear simulations of RF waves such as ion Bernstein wave in the cylindrical geometry [PoP13] and lower hybrid wave in the toroidal geometry [PPCF14]. Recently we have extended the cyclotron integrator in Boozer coordinates for simulation of the ion Bernstein and ion cyclotron modes in the toroidal geometry. Nonlinear simulation of the ion Bernstein wave and the lower hybrid wave in the toroidal geometry will be reported.
