The highlight of this presentation is the observation of energy-selective confinement of alpha particles during a sawtooth crash with near-unity safety factor. The underlying physics are explained in terms of a synergistic effect. Directions for further research are discussed., 15 th Japan-Korea Workshop on “Modeling and Simulation of Magnetic Fusion Plasmas”}, title = {Numerical Study of Kink-Interchange Sawtooth Crashes in a JET-shaped Plasma}, year = {2021} }
