Abstract
The energy absorption of RF waves at the spatial Alfven resonance of a cylindrical plasma is investigated numerically using ideal MHD equations. It is found that the absorbed power exhibits a resonant enhancement if a collective mode of the plasma response is excited. The dependence of the optimal power upon the characteristics of the plasma equilibrium, the type of the antenna-shell configuration and the type of the collective mode is studied.
