Non-inductive current drive in JET
Description
Full replacement of the inductively driven plasma current at 0.4 MA has been achieved with Lower Hybrid Current Drive only and at 2 MA with the combined application of 2.3 MW of LHCD power and 3 MW of Fast Wave power. Synergistic effects are observed resulting in an acceleration of the LHCD induced fast electrons by the Fast Wave. The physics of this synergy has yet to be resolved. In H-Mode conditions, 1 MA full current drive has been sustained for 4 sec. Overall current drive efficiencies up to 0.25 1020m-2 AW-1 have been achieved at n-bare = 2.8 1019m-3. Highly localised non-inductive currents have been produced by the Fast Wave resulting in large effects on MHD activity. Up to 0.4 MA of beam driven current has been produced with 133 keV tangential neutral beams. (author). 18 refs, 5 figs
