Current drive and current profile control on Tore Supra: a possible application for high energy negative ion‐based D0 injectors

Current drive and current profile control constitute one of the major lines of investigations on the 1.7 MA supra‐conducting Tokamak Tore Supra. Sixty seconds fully non‐inductive pulses were obtained in 1994 by means of Lower Hybrid current drive. A successful fast wave current drive programme is also ongoing. It is shown that D0 beams of 500–1000 keV, at a power level of 3–5 MW, would complete these physics investigations on the route of fully non‐inductive advanced Tokamak scenarios. The current drive efficiency, the fast ion losses and the shine‐through are calculated by means of a Fokker Planck code and a Monte‐Carlo code. The angle of injection and beam energy otimization calculations are presented. The results of the 2 codes are compared.
