Resistive damping of toroidicity induced Alfven eigenmode

Abstract

The MHD equations were used to study the resistive damping of the toroidicity induced Alfven eigenmode by employing the ballooning formalism. In the parameter regime in which the normalized plasma resistivity (n) is much less than the inverse aspect ratio (e), the equations are solved, by employing asymptotic techniques to yield a damping rate scaling gamma n/e{sup 2}. For n >> e{sup 3}, the damping rate is independent of e and scales as gamma n{sup 1/3}. The analytical results were verified numerically using a toroidal resistive MHD stability code.
