Martensitic stainless steels have been widely used in industries due to their high strength and good corrosion resistance performance. Precipitation-hardened (PH) martensitic stainless steels are featured by their very high strength compared with other stainless steels, around 3-4 times of the strength of austenitic stainless steels such as 304 and…

Drift kinetic stabilization of the resistive wall mode (RWM) is computationally investigated using the MHD-kinetic hybrid code MARS-K, following the non-perturbative approach [Liu et al., Phys. Plasmas 15, 112503 (2008)], for both reversed field pinch (RFP) and tokamak plasmas. Various kinetic resonances between the mode and the guiding center drif…

An unstable fishbone-like non-resonant external kink mode (FLEM) is numerically found to be driven by the precessional drift motion of trapped energetic particles (EPs) in both RFP and Tokamak plasmas. The FLEM originates from a stable external ideal kink mode, which is stabilized by a close-fitting ideal conducting wall. In the presence of a suffi…

The physics of kinetic effects on the resistive wall mode (RWM) stability is studied, and a comparison between reversed field pinch (RFP) and Tokamak configurations is made. The toroidal, magnetohydrodynamic (MHD)-kinetic hybrid stability code MARS-K, in which the drift kinetic effects are self-consistently incorporated into the MHD formulation, is…

Two issues of the resistive wall mode (RWM) control code maturity are addressed: the inclusion of advanced mode damping physics beyond the ideal MHD description, and the possibility of taking into account the influence of 3D features of the conducting structures on the mode stability and control. Examples of formulations and computational results a…
