Finite-n ballooning mode theory for axisymmetric toroidal plasmas

R.W. Moore, D. Dobrott

Abstract

Ballooning mode theory for finite toroidal mode number n is derived for shearfree and sheared axisymmetric toroidal plasmas. The resulting finite-n theory is applicable for both compressible and incompressible perturbations. The inclusion of finite compressibility changes the ballooning mode eigenfunctions and eigenvalues, but not the form of the finite-n correction.
