Quasi-linear evolution of tearing modes
Résumé
The growth of a tearing instability in Rutherford's non-linear regime is investigated. Using a singular perturbations technique, we recover to lowest order Rutherford's result. To the following order we show that the mode generates a quasi-linear deformation of the equilibrium flux profile, whose resistive diffusion slows down the growth and shows the possibility of a saturation of the instability.
