Stability of Axisymmetric Plasmas in Closed Line Magnetic Fields

The stability of axisymmetric plasmas confined by closed poloidal magnetic field lines is considered. The results are relevant to plasmas in the dipolar fields of stars and planets, as well as the Levitated Dipole Experiment, multipoles, Z pinches and field reversed configurations. The ideal MHD energy principle is employed to study the stability of pressure driven shear Alfvén modes. A point d...

Effects of three-dimensional electromagnetic structures on resistive-wall-mode stability of reversed field pinches.

In this Letter, the linear stability of the resistive wall modes (RWMs) in toroidal geometry for a reversed field pinch (RFP) plasma is studied. Three computational models are used: the cylindrical code ETAW, the toroidal MHD code MARS-F, and the CarMa code, able to take fully into account the effects of a three-dimensional conducting structure which mimics the real shell geometry of a reversed...

Modelling Resistive Wall Modes with Self-consistent Inclusion of Drift Kinetic Resonances

We investigate the effect of drift kinetic damping on the resistive wall mode (RWM), due to the mode resonance with magnetic precession drifts and/or bounce motion of bulk plasma thermal particles. A self-consistent toroidal drift kinetic model is developed and incorporated into the MHD code MARS-F [Y.Q. Liu, et al., Phys. Plasmas 7, 3681 (2000)]. The new code (MARS-K) is used to study the RWM ...

Three Dimensional Effects in Tokamaks – How Tokamaks Can Benefit From Stellarator Research

The paper deals with three dimensional effects in tokamaks that can be approximated by slowly varying 3d equilibria so that their theoretical description and corresponding code developments can benefit from stellarator research. We investigate the effect of magnetic field ripple and perturbation fields (magnetic islands, external coils) on fast particle orbits in ITER and ASDEX Upgrade equilibr...

Resistive Wall Mode Stabilization and Plasma Rotation Damping Considerations for Maintaining High Beta Plasma Discharges in NSTX

Maintaining steady fusion power output at high plasma beta is an important goal for future burning plasmas such as in ITER advanced scenario operation and a fusion nuclear science facility. Research on the National Spherical Torus Experiment (NSTX) is investigating stability and control physics to maintain steady high plasma normalized beta with minimal fluctuation. Resistive wall mode (RWM) in...
