Kinetic analysis of resistive wall modes in ITER

POSTER

Abstract

The stability of resistive wall modes (RWMs) is an issue of concern for ITER. So far several critical issues related to RWM stabilization in ITER have not been clarified, such as the coupling of the kinetic and shear Alfv\'en resonances, the parallel electric field effects, etc. To resolve these issues, we develop the AEGIS-K code, which features the adaptive numerical scheme for including the shear Alfv\'en resonance and the non-hybrid kinetic treatment based on our newly developed gyrokinetic theory [Phys. Plasmas {\bf 14}, 072505 (2007)]. The stability results will be presented, and the underlying physics will be discussed.
