Resonant theory of kinetic ballooning modes in general toroidal geometry
P. Mulholland, A. Zocco, M. C. L. Morren +4
The linear theory of the kinetic-ballooning-mode (KBM) instability is extended to capture a weakly-driven regime in general toroidal geometry where the destabilization is caused by…

Suppressing Trapped-Electron-Mode-Driven Turbulence via Optimization of Three-Dimensional Shaping
J. M. Duff, B. J. Faber, C. C. Hegna +2
Turbulent transport driven by trapped electron modes (TEMs) is believed to drive significant heat and particle transport in quasihelically symmetric stellarators. Two three-dimensi…

On the effect of flux-surface shaping on trapped-electron modes in quasi-helically symmetric stellarators
M. J. Gerard, M. J. Pueschel, B. Geiger +5
Using a novel optimization procedure it has been shown that the Helically Symmetric eXperiment (HSX) stellarator can be optimized for reduced trapped-electron-mode (TEM) instabilit…
