Global and Self-consistent Simulation of ICRF Heating in Toroidal Plasmas.

The ICRF heating in toroidal plasmas is studied using two global simulation codes: a full wave field solver TASK/WM and a drift kinetic equation solver GNET. The codes are applied to both tokamaks and helical systems. The full wave code TASK/WM evaluates the realistic wave electric field, in which the effect of the self-consistent non-Maxwellian velocity distribution on the wave propagation is taken into account. GNET solves a linearized drift kinetic equation (5D phase-space) for energetic ions including complicated behavior of trapped particles in helical systemsCharacteristics of energetic ion distributions in the phase space are investigatedSelf-consistent analysis including the effect of energetic ion distribution on the fast wave propagation is also reported for tokamak plasmas. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
