Abstract

The current drive efficiency has been evaluated for pure ICRF minority heating and for combined ICRF - NBI (where for the latter scheme j/P denotes the incremental efficiency associated with the RF interaction). For low RF power, the efficiencies for both schemes agree well with Fisch's qualitative estimate. The pure ICRF dropping dramatically for realistic power densities. This power dependence is much less pronounced for the combined scheme. Using typical JET discharge parameters, it is found that currents of the order of 2-4 MA could be driven with the planned ICRF and NBI capacity.
