Quasilinear Evolution of Multiple Non-thermal Ion Distributions in ICRF Heating

Self-consistent full-wave and Fokker-Planck simulations of wave heating in tokamaks have been generalized to include multiple energetic ion populations. To simplify the problem, it is assumed that, because of their low densities, the individual ion tails do not interact with each other in the Fokker...

Description
Summary:Self-consistent full-wave and Fokker-Planck simulations of wave heating in tokamaks have been generalized to include multiple energetic ion populations. To simplify the problem, it is assumed that, because of their low densities, the individual ion tails do not interact with each other in the Fokker-Planck solution. They do, however, interact self-consistently in the wave solution. Preliminary results are presented for DIII-D at 60 MHz and 116 MHz.
