Numerical Studies on Resistive Wall Instabilities in Cylindrical Plasma Confined by Surface Current

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 s...

Zusammenfassung: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.
