RF current drive by electron cyclotron waves in the presence of magnetic islands
The influence of the presence of magnetic islands, and the consequent modification of the tokamak magnetic surface topology, on electron cyclotron current drive is analyzed. To this end, a new three-dimensional Fokker-Planck code has been developed, taking into account the modifications of the magnetic equilibrium topology owing to the presence of the islands. Significant differences between the electron cyclotron current drive efficiency with and without islands inside the plasmas are found, particularly in the case of interaction with locked modes.
