LHCD Operation with ILW at JET

ITER is designed to operate with beryllium (Be) main wall and tungsten (W) divertor in order to comply with the requirements for low level of fuel retention. The necessity for better understanding of the plasma surface interactions and the underlying new physics initiated a project on installation of a new ITER Like Wall (ILW) at JET. Although currently not planned, a Lower Hybrid Current Drive (LHCD) system is still under consideration for ITER and this paper discusses important aspects of the performance of LHCD with ILW at JET for power levels up to 2.5MW.
