  • Energy description of wave-plasma interaction in the ion cyclotron range of frequency: Application to fast wave absorption and emission in tokamaks


An alternative description of the energy transfer between an electromagnetic wave and a tokamak plasma is presented. It involves the evaluation of local coefficients of emission and absorption and leads to rapid numerical procedures. This method allows a coherent description of emission and absorption processes and is thus particularly suited for the determination of the rf electromagnetic energy radiated from the plasma, as is shown by calculating ion cyclotron emission spectra. Furthermore, this fluid energy description proves also useful for the evaluation of the fast wave plasma absorption during ion cyclotron range of frequency (ICRF) heating: a fast fluid one-dimensional slab numerical code has been developed.
