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…
Flexible Stellarator Physics Facility
F. I. Parra, S. -G. Baek, M. Churchill +21
We propose to build a Flexible Stellarator Physics Facility to explore promising regions of the vast parameter space of disruption-free stellarator solutions for Fusion Pilot Plant…
Gyrokinetic investigation of toroidal Alfven eigenmode (TAE) turbulence
Ajay C. J., Ben McMillan, Arkaprava Bokshi +3
Toroidal Alfvén eigenmodes (TAEs) can transport fusion-born energetic particles out of the plasma volume, thereby decreasing plasma self-heating efficiency and possibly damaging re…
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…
Influence of collisions on trapped-electron modes in tokamaks and low-shear stellarators
M. C. L. Morren, J. H. E. Proll, J. van Dijk +1
The influence of collisions on the growth rate of trapped-electron modes (TEMs) in core plasmas is assessed through both analytical linear gyrokinetics and linear gyrokinetic simul…
