Unified theory of resistive and inertial ballooning modes in three-dimensional configurations
A linear stability theory of non-ideal MHD ballooning modes is investigated using a two fluid model for arbitrary three-dimensional electron-ion plasmas. Resistive-inertia ballooning mode (RIBM) eigenvalues and eigenfunctions are calculated for a variety of equilibria including axisymmetric shifted circular geometry (ŝ−α model) as well as for three dimensional configurations of interest relevan...
متن کاملUW-CPTC 09-8 Unified theory of resistive and inertial ballooning modes in three-dimensional configurations
Analytic results for the stability of resistive ballooning modes (RBMs) and electron inertial ballooning modes are obtained using a two-scale analysis. This work generalizes previous calculations used for axisymmetric ŝ− geometry [R.H. Hastie, J.J. Ramos and F. Porcelli Phys.Plasmas 10, 4405 (2003)] to general three-dimensional geometry. A unified theory is developed for RBMs and inertial ballo...
متن کاملUW-CPTC 09-7 Drift-resistive-inertial ballooning modes in the HSX Stellarator
A linear stability theory of non-ideal magnetohydrodynamic (MHD) ballooning modes is investigated using a two fluid model for electron-ion plasmas. Drift-resistive-inertial ballooning mode (DRIBM) eigenvalues and eigenfunctions are calculated for a variety of equilibria including axisymmetric shifted circular geometry (ŝ− model) as well as for three dimensional configurations relevant for the H...
متن کاملViscous, Resistive Magnetorotational Modes
We carry out a comprehensive analysis of the behavior of the magnetorotational instability (MRI) in viscous, resistive plasmas. We find exact, non-linear solutions of the non-ideal magnetohydrodynamic (MHD) equations describing the local dynamics of an incompressible, differentially rotating background threaded by a vertical magnetic field when disturbances with wavenumbers perpendicular to the...
متن کاملResistive wall modes and nonuniform wall rotation
The resistive wall mode ~RWM! poses a threat to many plasma confinement devices. The continuous rotation of the wall relative to the plasma makes it appear perfectly conducting, because of the skin effect, but this is ineffective if the perturbation locks to the wall. This raises the question of whether a nonuniformly rotating wall is more effective. In this paper we discuss the effect of such ...
