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…
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 tokama…
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…
