Quasi-single-stage optimization for advanced stellarators
Guodong Yu, Yidong Xie, Hengqian Liu +1
Advanced stellarator design requires a balance between plasma performance and the manufacturability of three-dimensional modular coils. In conventional two-stage optimization, the…
Optimized finite- tokamak-stellarator hybrid configurations achieved by planar dipole-field coils
Yihui Liang, Hengqian Liu, Guodong Yu +3
The paper presents a method for designing tokamak‑stellarator hybrid configurations using planar dipole‑field coils, optimizing coil currents and plasma parameters to achieve finit…
A programmable stellarator-tokamak hybrid for million-scale magnetic-configuration discovery
Guodong Yu, Xianyi Nie, Gwanggeun Seo +10
Tokamaks and stellarators are the leading magnetic-confinement concepts for fusion, but they rely on complementary design principles. Tokamaks use simple axisymmetric coils and pla…
Optimizing stellarators with hidden symmetry
Hengqian Liu, Guodong Yu, Caoxiang Zhu +8
Stellarators confine fusion plasmas using three-dimensional magnetic fields composed of nested toroidal magnetic surfaces. In generic stellarators, trapped particles can drift acro…
Combination of quasi-isodynamic and piecewise omnigenous magnetic fields
J. L. Velasco, I. Calvo, V. Fernández-Pacheco +5
Due to their simultaneous optimization for radial and parallel neoclassical transport, quasi-isodynamic fields have been the main choice of stellarator magnetic configuration for m…
Optimization of stellarator configurations combining omnigenity and piecewise omnigenity
Hengqian Liu, Guodong Yu, José Luis Velasco +1
We present a method for optimizing stellarator configurations that combine omnigenity and piecewise omnigenity (pwO). Within the \texttt{OOPS} optimization framework [Liu \textit{e…
