MHD normal mode analysis with equilibrium pressure anisotropy

Fitzgerald, M; Hole, Matthew; Qu, Z S


In this work, we generalise linear magnetohydrodynamic (MHD) stability theory to include equilibrium pressure anisotropy in the fluid part of the analysis. A novel ‘single-adiabatic’ (SA) fluid closure is presented which is complementary to the usual ‘double-adiabatic’ (CGL) model and has the advantage of naturally reproducing exactly the MHD spectrum in the isotropic limit. As with MHD and CGL, the SA model neglects the anisotropic perturbed pressure and thus loses non-local fast-particle...[Show more]
