Recent Heating and Current Drive Results on JET in View of ITER

Recent progress in heating and current drive on JET in preparation of ITER is summarized. The paper reports new results on the following topics: high power coupling of Ion Cyclotron Resonant Heating/Lower Hybrid Current Drive (ICRF/LHCD) at ITER relevant antenna/launcher-separatrix distances, use of 3dB couplers for ELM tolerance of the ICRF system, influence of ICRF on LHCD operation, fast beam ion transport, rotation studies in plasma without external momentum with standard and enhanced JET toroidal field ripple, studies of different ICRF heating schemes and of Neoclassic Tearing Modes (NTM) avoidance schemes using Ion Cyclotron Current Drive (ICCD). Future plans for further tests and developments of load tolerant ICRF systems at JET are presented.
