High Confinement and High Density with Stationary Plasma Energy and Strong Edge Radiation in the TEXTOR-94 Tokamak

Journal Article · · Physical Review Letters
Stationary high energy confinement is observed on TEXTOR-94 for times limited only by the flux swing of the transformer using strong edge radiation cooling. Necessary tools are the feedback control of the radiated power and of the plasma energy content. At the highest densities obtained (up to 1.2 times the Greenwald limit), energy confinement exceeds the edge-localized-mode-free {ital H}-mode scaling ITERH93-P by more than 20{percent}. {beta} limits of TEXTOR-94 are reached with {ital f}{sub H89}/{ital q}{sub {ital a}}{approx_equal}0.6. No detrimental effect of the seeded impurity is seen. These high confinement discharges meet many conditions necessary for a fusion reactor regime. {copyright} {ital 1996 The American Physical Society.}
