The Stability

The stability of resistive wall mode is studied in cylindrical plasma confined by surface current, which is Dirac -function distribution. For Dirac -function distribution case, it is shown that the perturbations oscillate and even decline wherever the initial perturbation seed is placed. The whole system is stable and the plasma flow has little effect on it.

AbstractStability of the resistive wall mode in cylindrical plasmas confined by surface currents is investigated for the δ-function and step-function equilibrium surface-current profiles. For the former, it is shown that the perturbations oscillate and even decay for all locations of the initial perturbation. The entire system is stable and the plasma flow has little effect. For the step-function surface-current distribution, it is found that the thicker the surface current layer, the more stable is the system even if the largest initial perturbation is located on the rational surface, but the plasma flow also has little effect on the system.
