Abstract
The main aspects of heating with the fast wave in the ion cyclotron range of frequencies (ICRF) are reviewed. First, the ion cyclotron resonance mechanism, fundamental and harmonics, is examined. Then the properties of fast wave dispersion are reviewed, and the principles of minority and higher cyclotron harmonic heating are discussed. An elementary coupling model is worked out in order to outline the computation of the electrical properties of ICRF antennas. Using the same simple model, the antenna radiation pattern inside the plasma is computed and the effect of phasing on the k∥ spectrum and on the antenna radiation properties is illustrated. The quasilinear-Fokker-Planck computation of the deformation of distribution function due to Radio-Frequency (RF) and tail formation are briefly discussed.
