AERH: A New RF Heating Scheme

摘要

Recent experimental and theoretical studies have revealed the existence, in a current-carrying plasma, of hitherto unknown global eigenmodes of the Alfven wave (discrete Alfven spectrum). The potential for a new RF heating scheme using the resonant excitation of such modes in Tokamaks, the Alfven Eigenmode Resonance Heating (AERH) is explored. It is concluded that such a heating scheme is most efficient for axisymmetric excitation (toroidal mode number n = 0). In this case the antenna load is one to two orders larger than that of resonant absorption scheme of Alfven Wave Heating. (ERA citation 08:042934)
