Stationary plasma discharges at high level of heating power, combining lower hybrid waves (LHCD) and ion cyclotron resonance heating (ICRH), during more than 10 seconds have been achieved during the 2004 Tore Supra campaign. These high power flux discharges had a density near or above the Greenwald limit, and had in many cases a non-inductive current fraction of 100%. The discharge were sustained in a safe and stable way, with respect to:
- Thermal Behaviour of all actively cooled RF launchers (Three ICRH antennas, two LH launchers), observed by infrared cameras
- Electron and ion temperatures, density and current profiles (during the flat top)
- The present paper describes the discharges and their analysis by means of integrated simulation code CRONOS. The effect of hydrogen injection to control the isotopic fraction during the H minority ICRF heating, and its impact on the level of bilk ion heating also examined.
