Minimum-q induced alternation between infernal modes and EP-driven modes in advanced tokamak configurations
Shiwei Xue, Ping Zhu, Haolong Li
For an advanced tokamak configuration in the presence of energetic particles (EPs), the dominant instability is found to alternate between infernal modes and Alfvén eigenmodes with…
Influence of plasma shaping on the parity of core-localized toroidal Alfvén eigenmode in an advanced tokamak configuration
Shiwei Xue, Ping Zhu, Haolong Li
Toroidal Alfvén eigenmodes (TAEs) and energetic particle modes (EPMs) can both be excited by energetic particles from auxiliary heating and fusion-born alpha particles in a tokamak…

Yiming Ma, Ping Zhu, Bo Rao +1
The nonlinear evolution of the tilt instability in a field reversed configuration (FRC) during the dynamic magnetic compression process has been investigated using magnetohydrodyna…
Enhanced dynamo drive for the sawtooth relaxation process due to non-uniform resistivity distribution in a reversed field pinch
Wentan Yan, Ping Zhu, Hong Li +3
In this work, we use the three-dimensional resistive MHD code NIMROD to investigate the impact of resistivity inhomogeneity on the sawtooth process of an reversed field pinch (RFP)…
Invariant regimes of Spencer scaling law for magnetic compression of rotating FRC plasma
Yiming Ma, Ping Zhu, Bo Rao +1
The scaling laws for the magnetic compression of a toroidally rotating field reversed configuration (FRC) have been investigated in this work. The magnetohydrodynamics (MHD) simula…
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…
MHD Simulations on Magnetic Compression of Field Reversed Configurations
Yiming Ma, Ping Zhu, Bo Rao +1
The magnetic compression has long been proposed a promising method for the plasma heating in a field reversed configuration (FRC), however, it remains a challenge to fully understa…
Two-dimensional shaping of Solov'ev equilibrium with vacuum using external coils
Jiaxing Liu, Ping Zhu, Haolong Li
In this work, we demonstrate a method for constructing the Solov'ev equilibrium with any given 2D shape surrounded by a vacuum region using external poloidal field coils. The compu…
MHD analysis on the physical designs of CFETR and HFRC
Ping Zhu, Li Li, Yu Fang +32
The China Fusion Engineering Test Reactor (CFETR) and the Huazhong Field Reversed Configuration (HFRC), currently both under intensive physical and engineering designs in China, ar…
Formation of edge pressure pedestal and reversed magnetic shear due to toroidal rotation in a tokamak equilibrium
Haolong Li, Ping Zhu
Toroidal rotation is well known to play significant roles in the edge transport and L-H transition dynamics of tokamaks. Our recent calculation finds that a sufficiently strong loc…
Cold bubble formation from 2/1 tearing mode during massive gas injection in a tokamak
Shiyong Zeng, Ping Zhu, V. A. Izzo +2
Massive gas injection (MGI) experiments have been carried out in many tokamaks to study disruption dynamics and mitigation schemes. Two events often observed in those experiments a…
