Collisional dependence of Alfven mode saturation in tokamaks

M Zhou & R White
Saturation of \alfven modes driven unstable by a distribution of high energy particles as a function of collisionalityis investigated with a guiding center code, using numerical eigenfunctions produced by linear theory and numerical high energy particle distributions. The most important resonance is found and it is shown that when the resonance domain is bounded, not allowing particles to collisionlessly escape, the saturation amplitude is given by the balance of the resonance mixing time with the...
