Neoclassical transport processes are important to the understanding of plasma confinement
physics in doubly periodic magnetized toroidal plasmas, especially, after the impact of the …

An integrated study of compact stellarator power plants, ARIES-CS, has been conducted to
explore attractive compact stellarator configurations and to define key research and …

Abstract The Chinese First Quasi-axisymmetric Stellarator (CFQS) will be the first
operational quasi-axially symmetric stellarator in the world. The physical and engineering …

Toroidal symmetry is an important concept for plasma confinement; it allows the existence of
nested flux surface MHD equilibria and conserved invariants for particle motion. However …

Novel stellarator configurations have been developed for ARIES-CS. These configurations
are optimized to provide good plasma confinement and flux surface integrity at high beta …

The quasi-poloidal stellarator (QPS) hybrid has been developed using a stellarator
optimization approach that has proven to be compatible with both low aspect ratio and …

In the framework of fusion energy research based on magnetic confinement, pulsed high-
field tokamaks such as Alcator and FTU have made significant scientific contributions, while …

Characteristics of modular coils for quasi-axisymmetric stellarators that are related to the
plasma aspect ratio, number of field periods and rotational transform have been examined …

A method for computing the ideal magnetohydrodynamic (MHD) stability boundaries in three-
dimensional equilibria is employed. Following Hegna and Nakajima [Phys. Plasmas 5, 1336 …

By varying the pressure-gradient and average shear at a selected surface in a given
arbitrary stellarator equilibrium and by inducing a coordinate variation such that the …
