A lower hybrid current drive model which takes into account a dc electric field has been developed. The model is based on the Fokker-Planck equation, plasma circuit equation and power balance equations. Simulation results qualitatively agree well with those of the experiments.
The finite element library PDE-PROTRAN is applied for the numerical solution of a quasilinear two-dimensional Fokker-Planck equation to study the cross-effect of electron cyclotron heating and lower-hybrid current drive in tokamak plasmas. Results show that the current drive efficiency of EC waves i
