Prof. Yoon Gun-su’s team (PHYS), cooperated with Prof. Park Hyeon-kyu’s team (PHYS) from UNIST and National Fusion Reaction Institute (NFRI)’s Korea Superconducting Tokamak Advanced Research (KSTAR) Center. They discovered an isolated perturbation that takes place right before the plasma surface explosion inside the tokamak. The process of generation of such perturbation was also investigated. This was notable to academia as it suggested a new analysis that plasma surface explosion is caused by isolated perturbation, revealing the limits of the established eigen mode based interpretation. The breakthrough brings new hope in understanding the mechanism of plasma surface explosion, which has been one of the conundrums of nuclear fusion related research. The research team is currently analyzing the intense electromagnetic wave that accompanies the surface explosion.
