Effects of kinetic resonances on the stability of resistive wall modes in reversed field pinch

• The kinetic effects, due to the mode resonance with thermal particle driftmotions in the reversed field pinch (RFP) plasmas, are numerically investigatedfor the stability of the resistive wall mode, using a non-perturbative MHD-kinetic hybrid formulation. The kinetic effects are generally found to be tooweak to substantially change the mode growth rate, or the stability margin, re-enforcing the fact that the ideal MHD model is rather adequate for describingthe RWM physics in RFP experiments.
