ANALYSES OF ICRF WAVES ON JET PLASMAS
Theoretical and computational study of ICRF waves has been done for JET plasmas. Present experiments are done by combination use of two kinetic codes. The wave field is solved for obtaining the power disposition profile of each plasma species and the antenna impedance. Two-ion hybrid case is simulated. Strong minority heating in central core region is observed and the direct input to electrons is found at most 10% of the total absorption. However, for the higher temperature target plasma, the deposition profile to electrons becomes broader and off-central and its input reaches - 30%. Efficient non-central deposition to ions by combined use of NBI is also discussed. Global coupling study is also done for cold plasma with dampings.
