Ideal MHD normal mode equations of axisymmetric toroidal plasmas
Description
The ideal MHD normal mode equations for axisymmetric plasmas can be significantly simplified in two limiting cases: ω2 <>k//2cs2(k// is the longitudinal wave number, cs the sound wave velocity). These equations, describing the general global modes (low n, m modes), contain only two scalar functions. For tokamak plasmas, a further simplification by introducing the shear-Alfven approximation makes it possible to describe the global mode by a single scalar function. The resultant equation can be used to analyse the kink, Alfven spectrum, and the TAE gap modes
