Feedback and rotational stabilization of resistive wall modes in ITER

• Different models have been introduced in the stability code MARS-F in order tostudy the damping effect of resistive wall modes (RWM) in rotating plasmas. Benchmarkof MARS-F calculations with RWM experiments on JET and D3D indicates thatthe semi-kinetic damping model is a good candidate for explaining the dampingmechanisms. Based on these results, the critical rotation speeds required forRWM stabilization in an advanced ITER scenario are predicted. Active feedbackcontrol of the $n=1$ RWM in ITER is also studied using the MARS-F code.
