Effects of kinetic resonances on the stability of resistive wall modes in reversed field pinch
Artikel i vetenskaplig tidskrift, 2011

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