Abstract

The full set of the usual resistive massless equations is used to investigate the non linear growth of the helical perturbations to a cylindrical equilibrium with Tokamak ordering. There is a curvature dependant critical magnetic island width x***-T varies as /D/DELTA'/ above which the Rutherford solution is recovered for the tearing mode as well as for the linear slow interchange modes with DELTA' > O. Non linearity stabilizes at this critical width the linearly unstable slow interchange modes with DELTA' > O.
