Optimized finite- tokamak-stellarator hybrid configurations achieved by planar dipole-field coils
Yihui Liang, Hengqian Liu, Guodong Yu +3
Tokamak--stellarator hybrids seek to combine tokamak-like compactness and confinement with stellarator-like externally generated rotational transform and steady-state operation. In…
Nonlinear magnetohydrodynamic modeling of ideal ballooning modes in high- Wendelstein 7-X plasmas
Yao Zhou, K. Aleynikova, Chang Liu +1
We present nonlinear magnetohydrodynamic (MHD) simulations of high- Wendelstein 7-X plasmas using the stellarator extension of the M3D- code, building on the recent work th…
Available Energy and Ground States of Convective Hydrodynamic and Hydromagnetic Instabilities
Kaixuan Fan, Yao Zhou
We propose a method for predicting the nonlinear saturation level of convective instabilities in neutral and magnetized fluids. The method combines Gardner's restacking algorithm,…
Benign saturation of ideal ballooning instability in a high-performance stellarator
Yao Zhou, K. Aleynikova, Chang Liu +1
To examine the robustness of the designed 5% -limit for high-performance operation in the W7-X stellarator, we undertake nonlinear magnetohydrodynamic (MHD) simulations of press…
