An intensive integrated modelling work of main scenarios of the new tokamak DTT (Divertor Tokamak Test facility) with the Single Null divertor configuration has been performed using first-principle quasi-linear transport models, in support to the design of the device and to the definition of its scientific work-programme. First results of this i…

Progress in understanding lower hybrid current drive (LHCD) at high density has been made through experiments and modeling, which is encouraging given the need for an efficient off-axis current profile control technique in burning plasma. By reducing the wall recycling of neutrals, the edge temperature is increased and the effect of parametric inst…

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 …
