Abstract
The ideal MHD normal mode equations for general toroidal axisymmetric plasmas can be significantly simplified by properly treating the compressibility term in two limiting cases. The simplified equations, describing the general global modes (the low n, m mode), contain only two scalar functions. For tokamak plasmas, a further simplification, the shear Alfven approximation, is introduced, it makes possible to describe the global mode by a simplified eigenmode equation with only one scalar function. This eigenequation, similar to the reduced tokamak equations widely used in recent literatures, provides and unified way to analyze the kink, Alfven spectrum and MHD TAE (toroidal Alfven eigenmode) modes.
