Abstract

A theoretical and a computational study of ICRF waves were conducted for JET plasma. The present experimental parameters are analysed and various prediction studies for future experiments are considered using a combination of two kinetic codes. The wave field was solved for obtaining a power deposition profile of each plasma species and the antenna impedance. A two-ion hybrid case was simulated. Strong minority heating in the central core region was observed and a direct input to electrons was found at most 10% of the total absorption. However, for the higher-temperature target plasma, the deposition profile to the electrons became broader and the off-center and its input reached 30%. An efficient non-central deposition to ions by a combined use of NBI is also discussed. A global coupling study is also given for a cold plasma with dampings.
