Abstract

Disruption is one of the most critical issues in tokamaks. A resonance magnetic perturbation (RMP) coil system will be installed in future tokamaks such as the International Thermonuclear Experimental Reactor to mitigate edge localized modes. In this study, the effect of RMP on tokamak disruption was investigated using the small tokamak device HYBTOK-II. It was found statistically that an externally applied RMP leads to faster current quench during disruption.
