On shear Alfvén wave-induced energetic ion transport in optimized stellarators
A. R. Knyazev, A. Lachmann, A. G. Goodman +4
In this work, we investigate prompt ion drift orbit losses caused by shear Alfvén waves (SAW) in quasi-symmetric (QS) and quasi-isodynamic (QI) stellarators optimized for equilibri…
Quasi-isodynamic stellarators with low turbulence as fusion reactor candidates
Alan G. Goodman, Pavlos Xanthopoulos, Gabriel G. Plunk +7
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 m…
Optimised stellarators with a positive radial electric field
Per Helander, Alan G. Goodman, Craig D. Beidler +2
We draw attention to an interesting possibility in the design and operation of stellarator fusion reactors, which has hitherto been considered unrealistic under burning-plasma cond…
The maximum- property in quasi-isodynamic stellarators
E. Rodriguez, P. Helander, A. G. Goodman
Some stellarators tend to benefit from favourable average magnetic curvature for trapped particles when the plasma pressure is sufficiently high. This so-called maximum--propert…
Constructing precisely quasi-isodynamic magnetic fields
Alan Goodman, Katia Camacho Mata, Sophia A Henneberg +6
We present a novel method for numerically finding quasi-isodynamic stellarator magnetic fields with excellent fast-particle confinement and extremely small neoclassical transport.…
