| 内容記述 | The MHD-PIC hybrid code MEGA has recently reproduced sequences of so-called Abrupt Large Events (ALE) as observed in JT-60U. ALEs are important because they cause a significant amount of particle transport, and the recent hybrid simulations offer a way to study the underlying physical processes. Here, we report the latest insights obtained from Poincaré analyses of the magnetic topology during simulated ALEs. In particular, it is found that magnetic islands form during ALEs in the simulation. Potentially important implications for the transport and confinement of both the thermal background plasma and energetic ions are discussed. | |||||
