Abstract

Fast wave current drive, FWCD, has been performed in JET plasmas with internal transport barriers, ITBs. The heating during the FWCD is strongly degraded compared to dipole heating. The FWCD has only a small effect on the central current density. The main reasons are the parasitic absorption of RF power, the strongly inductive nature of the plasma and the interplay between the fast wave driven current and bootstrap current.
