A comparison of low-n Mercier unstable Wendelstein stellarators and quasi-interchange modes in tokamaks
Rohan Ramasamy, Haowei Zhang, Joachim Geiger +5
Mercier's criterion is typically enforced as a hard operational limit in stellarator design. At the same time, past experimental and numerical studies have shown that this limit ma…

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…

Suppression of turbulence by trapped electrons in optimised stellarators
J. H. E. Proll, P. Xanthopoulos, P. Helander +5
In fusion devices, the geometry of the confining magnetic field has a significant impact on the instabilities that drive turbulent heat loss. This is especially true of stellarator…
