摘要：

Recent results on feedback control of the global shape of the current density profile in discharges with lower hybrid current drive (LHCD) on Tore Supra are presented. The global shape of the current density profile is characterized by its internal inductance ii, and feedback controlled through the LH power or the launched LH wave spectrum. Feedback control of the Aux on the plasma boundary has allowed for exploration of regimes with partial current drive (constant loop voltage) and full current drive (zero loop voltage). In stationary, steady state discharges at 0.8 MA (q(a) = 7), the current profile shape is characterized by an l(i) between 1.5 and 1.7 and a safety factor on-axis (q(0)) between 1 and 1.4. The energy confinement is 1.3 to 1.6 times higher than the value predicted by the Rebut-Lallia-Watkins scaling law.
