ITER relevant ICRF heating scenarios with large ion heating fraction
Autor: L.-G. Eriksson, D.F.H. Start, V. Bergeaud
Publikováno v: Nuclear Fusion. 40:35-51
The merits of a large ion heating fraction for the performance of a tokamak reactor are investigated. The abilities of different ICRF heating scenarios in providing significant ion heating are discussed. The 3He minority scenario is found to be the m
