Stabilization of the Resistive Wall Mode Instability by Trapped Energetic Particles
TL;DR: A theoretical model for investigating the effect of trapped energetic particles (EPs) on the resistive wall mode (RWM) instability is proposed in this article, where the authors demonstrate that the trapped EPs have a dramatic stabilizing effect on the RWM because of resonant interaction between the mode and the magnetic precession drift motion of the trapped particles.
Journal ArticleDOI
3D effects on RWM physics in RFX-mod
M. Baruzzo,Tommaso Bolzonella,S. C. Guo,Yueqiang Liu,Giuseppe Marchiori,Roberto Paccagnella,Anton Soppelsa,Fabio Villone,Zhirui Wang +8 more
TL;DR: The behavior of resistive wall modes (RWMs) in the RFX-mod reversed field pinch device is studied in this article, with a focus on 3D issues in the characterization of the m spectrum of the mode and on the study of multi-harmonic coupling.
Journal ArticleDOI
An improved method to evaluate the ideal no-wall beta limit from resonant field amplification measurements in JET
Yueqiang Liu,I. T. Chapman,S. Saarelma,Mikhail Gryaznevich,T. C. Hender,D. F. Howell,Jet-Efda Contributors +6 more
TL;DR: In this article, a new way of determining the RFA threshold, based on evaluating the logarithmic derivative of the amplitude as a function of the normalized plasma pressure, was proposed.
Journal ArticleDOI

TL;DR: In this paper, an active resistive wall mode (RWM) feedback control was evaluated using highly reproducible current-driven RWMs in ohmic discharges in DIII-D. The use of derivative gain on top of proportional gain was found to be advantageous.
Journal ArticleDOI
Effects of kinetic resonances on the stability of resistive wall modes in reversed field pinch
TL;DR: In this paper, the stability of the resistive wall mode was investigated using a non-perturbative MHD-INE hybrid formulation, and the kinetic effects were generally found to be too weak to substantially change the mode growth rate, or the stability margin.
