Title: Kinetic calculation of the resistive wall mode and fishbone-like mode instability in tokamak

Abstract

Kinetic effects of both trapped thermal and energetic particles on the resistive wall mode (RWM) and on the fishbone-like mode (FLM) are investigated in theory. In this paper, the trapped thermal particles include both ions and electrons. The FLM is driven by trapped energetic particles. The results demonstrate that thermal particle collisions can either stabilize or destabilize the RWM, depending on the energetic particle pressure β h . Furthermore, the critical value of β h for triggering the FLM is increased when the thermal particle contribution is taken into account. Finally, the critical value sensitively depends on the plasma collision frequency. In addition, the plasma inertia is found to have a negligible influence on the FLM.
