Quasilinear stabilization of ballooning modes in toroidal plasma systems
Zakharov L. E., Riedel K., Semenov S. B.
An equation describing the quasilinear saturation of ballooning modes in toroidal configurations is derived. The ballooning instabilities are effectively stopped because the pressure profile near resonant surfaces becomes flattened as a result of the formation of magnetic islands. There is no fundamental change in the structure of the overall magnetic configuration.
