Deuterium plasmas with a current of 1 MA, having quasi-stationary conditions for one minute, were obtained in TORE SUPRA, a large superconducting tokamak. The plasma current was partially noninductively driven by a 2.5 MW, 62 s lower hybrid wave pulse, resulting in a high central electron temperature (5.5 keV) for a plasma with a central electron density of 3.5 × 1019 m-3
