A novel scheme for error field correction in permanent magnet stellarators
Stellarators offer a promising path towards fusion reactors, but their design and construction are complicated by stringent tolerance requirements on highly complex 3D coils. A potential way to simplify the engineering requirements for stellarators is to

Drift waves in stellarator geometry [PDF]
Drift waves are investigated in a real three-dimensional stellarator geometry. A linear system, based on the cold ion fluid model and a ballooning mode formalism, is solved numerically in the geometry of the stellarator H1-NF.

Exploration of the parameter space of piecewise omnigenous stellarator magnetic fields
Piecewise omnigenous fields are stellarator magnetic fields that are optimized with respect to radial neoclassical transport thanks to a second adiabatic invariant that is piecewisely constant on the flux-surface.

Quasi-Isodynamic Stellarators with Low Turbulence as Fusion Reactor Candidates
The stellarator is a type of fusion energy device that—if properly designed—could provide clean, safe, and abundant energy to the grid. To generate this energy, a stellarator must keep a hot mixture of charged particles (known as a plasma) sufficiently ...
