Abstract

The addition of rf heating to an NBI-driven target discharge is observed to reduce the toroidal rotation frequency. Experiments on this effect were performed on JET using (H)-D and ({3}He)-D minority ICRH to vary the bulk electron to ion heating ratio. However, to lowest order, there is no clear difference in the two heating scenarios. We apply a recent model of Nishijima et al. [4] based upon the degradation of confinement with auxiliary power, and find that these JET data are in reasonable agreement with it.
