Abstract

The achievement and control of steady-state transport barriers under dominant electron heating is a challenging reactor relevant objective, owing to the damping channel on the electron population that is expected for alpha-particles. For this purpose, many studies have been carried out in TORE SUPRA, using the Lower Hybrid (LH) wave which is so far the most efficient method to drive a current in the plasma and control its radial profile. The key point is to determine unambiguously the relationship between q-profile shaping, transport properties but also robustness of the improved regime against MHD stability, the latter being especially important in the frame of steady-state operation. A review of the experimental results and data analysis is presented.
