Lower Hybrid waves have shown to have a high current drive (CD) efficiency suitable for current profile modification [1, 2]. These results were obtained at rather low density. Recent results on C-Mod [3], FTU [4] and JET [5, 6] indicate that CD efficiency could decrease at high density. On JET, the analysis of the contribution of fast electrons to …


The impact of the Radio Frequency heating and current drive systems on the ITER advanced scenarios is analyzed by means of the CRONOS suite of codes for integrated tokamak modelling. As a first step, the code is applied to analyze a high power advanced scenario discharge of JET in order to validate both the heating and current drive modules and the…
