Some novel features of the ordinary-mode electron-cyclotron resonance heating of tokamak plasmas
Abstract
It is shown that the finite k/sub parallel/ linear theory of absorption predicts: first, that the Doppler effect splits the k/sub parallel/ = o resonance into two closely spaced resonances instead of the usual Gaussian broadening; and second, that although the total absorption is due to the finite size of the electron Larmor orbits, it is mainly determined by T/sub parallel/ and is only weakly dependent on T/sub perpendicular/ via cyclotron overstability type terms. Some consequences of these unique features on plasma heating and rf current drive are also examined.
