Resistive wall mode induced disruptions in an advanced tokamak
Sui Wan, Ping Zhu
Resistive wall mode is one of the leading causes for tokamak disruptions above the no-wall limit. This paper presents nonlinear three-dimensional resistive MHD simulations o…
Weak and reversed magnetic shear effects on internal kink and fishbone modes
Weikang Cai, Ping Zhu, Zhi Zhang +2
Advanced tokamak scenarios often feature weak or reversed magnetic shear configurations. In this study, the hybrid kinetic-MHD model implemented in the NIMROD code is used to inves…
Auroral signatures of ballooning instability and plasmoid formation processes in the near-Earth magnetotail
Ping Zhu, Jun Liang, Jiaxing Liu +2
The nonlinear development of ballooning instability and the subsequently induced plasmoid formation in the near-Earth magnetotail demonstrated in MHD simulations has been proposed…
Effects of reversed magnetic shear on the plasma rotation stabilization of resistive wall modes in tokamaks
Sui Wan, Ping Zhu, Linjin Zheng
Effects of reversed magnetic shear on the plasma rotation stabilization of resistive wall modes in tokamaks are investigated using the AEGIS code. MHD equilibria in toroidal config…
