Effects of zero and reversed magnetic shear on resistive wall modes in a limiter tokamak plasma
Sui Wan, Ping Zhu, Haolong Li +1
Advanced tokamak scenarios often feature equilibriums with zero and reversed magnetic shear. To isolate and investigate their impacts on the resistive wall mode (RWM) instability a…
Roles of non-axisymmetric perturbations in free drift vertical displacement events on EAST
Haolong Li, Ping Zhu, Hang Li +3
The safe operation of most tokamaks, especially the largen sized ones, rely on the feedback control of the vertical displacement events (VDEs). However, most these feedback control…
A weighted matching scheme of magnetic coil design for FRC shaping control
Zitong Qu, Ping Zhu, Zhipeng Chen +2
The two-dimentional (2D) separatrix shaping plays a crucial role in the confinement of the Field Reversed Configuration (FRC), and the magnetic coils serve as an effective means fo…
Stabilizing effects of resistivity on low-n edge localized modes in NSTX
Debabrata Banerjee, Ping Zhu, Rajesh Maingi
The stabilizing effects of enhanced edge resistivity on the low-n edge localized modes (ELMs) are reported for the first time in the context of ELM suppression in H-mode discharge…
