Description
On TORE SUPRA it has been experimentally found that the ergodization of magnetic field lines on a thin layer (0.1-0.2 m) at the plasma boundary has a strong stabilizing effect on the m=2 n=1 tearing mode. This is observed on a wide range of edge safety factor (2.5<qψ(a)<4.5) and of internal inductance (0.8<li<1.6). This stabilizing effect has been successfully used to prevent both density limit disruptions and the disruptions triggered by mode locking in fast plasma current rises. A set of experimental data is reported in this paper. (author) 9 refs., 4 figs
