Hybrid kinetic-MHD simulation on the formation of runaway electron current plateau during a current quench process
Weimin Fu, Ping Zhu
Runaway electron (RE) generation is of great concern for high-current tokamak operations. A full-f particle-in-cell (PIC) model for RE dynamics has been developed and coupled with…
Identification of MHD equilibrium limits for CFQS plasmas
Jian Zhang, Ping Zhu, Haifeng Liu +3
The magnetohydrodynamic (MHD) equilibrium limits in the Chinese First QuasiAxisymmetric Stellarator (CFQS) are investigated using the NTEC code, for both the standard and the m…
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…
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…
MHD simulation of tilt instability during the dynamic FRC magnetic compression process
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…
Numerical solutions of resistive finite-pressure magnetohydrodynamic equilibria for non-axisymmetric toroidal plasmas
Jian Zhang, Ping Zhu, Chris C. Hegna
A hybrid spectral/finite-element code is developed to numerically solve the resistive finite-pressure magnetohydrodynamic equilibria without the necessity of postulating nested mag…
Impurity radiation seeding of neoclassical tearing mode growth
Shiyong Zeng, Ping Zhu, Eric C. Howell
The physics of neoclassical tearing mode (NTM) is of great concern to the tokamak plasma stability and performance, especially in the burning plasma regime. Whereas a great deal ab…
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…
Viscous effects on plasmoid formation from nonlinear resistive tearing growth in a Harris sheet
Nisar Ahmad, Ping Zhu, Ahmad Ali +1
In this study, the evolution of a highly unstable m = 1 resistive tearing mode, leading to plasmoid formation in a Harris sheet is studied in the framework of full MHD model using…
