A quasi-axisymmetric stellarator, the CFQS, has been designed as a joint project of the
National Institute for Fusion Science and Southwest Jiaotong University to prove intrinsic …

An international stellarator database on global energy confinement is presented. It
comprises a total of 859 discharges from the ATF, CHS and Heliotron-E heliotron/torsatrons …

Numerical results for the three mono-energetic transport coefficients required for a complete
neoclassical description of stellarator plasmas have been benchmarked within an …

Excerpt This book project arose out of the collaboration on Hidden Symmetries and Fusion
Energy1 funded by the Simons Foundation, initially between 2018 and 2022 and then for a …

In recent years, helical plasma research has progressed greatly. The deuterium operation of
the Large Helical Device (LHD) begun in March, 2017 [1–4] to explore a higher-performance …

Abstract The Compact Toroidal Hybrid (CTH) is a low-aspect-ratio (), low-beta (%) torsatron
with a major radius of. CTH is operable as a pure stellarator, but most research on this …

This review is devoted to the theory of plasma equilibrium in conventional stellarators with a
plane circular axis and helical magnetic fields. Its primary objectives are the analysis of the …

The high‐n helicity‐induced shear Alfvén eigenmodes (HAE) are considered both
analytically and numerically for the straight helical magnetic system, where n is the toroidal …

Confining energetic ions such as alpha particles is a prime concern in the design of
stellarators. However, directly measuring alpha confinement through numerical simulation of …

High beta plasmas with a volume averaged equilibrium beta value of 2.1% were produced
in CHS using tangential neutral beam injection. This beta value was achieved with the …
