Numerical and diagnostic extensions to the gyrokinetic code stella
Sven Stroteich, Georgia Acton, Michael Barnes +2
Understanding turbulence in magnetised plasmas requires robust numerical tools capable of capturing complex free-energy transfer processes across scales. We demonstrate the utility…
Enhanced performance in quasi-isodynamic max- stellarators with a turbulent particle pinch
G. G. Plunk, A. G. Goodman, P. Xanthopoulos +7
Recent stellarator reactor designs demonstrate mostly outward turbulent particle transport, which, without advanced fueling technology, inhibits the formation of density gradients…
Critical gradient optimization for quasi-isodynamic stellarators
G. T. Roberg-Clark, P. Xanthopoulos, G. G. Plunk +1
We present new and updated methods for reducing transport caused by electrostatic ion temperature gradient (ITG) driven turbulence in quasi-isodynamic (QI) configurations. We first…
Zonal flow suppression of turbulent transport in the optimized stellarators W7-X and QSTK
Abhishek Tiwari, Joydeep Das, Jaya Kumar Alageshan +6
We present a comparative study of transport in two optimized stellarator configurations: Wendelstein 7-X (W7-X) and a recent design called Quasi-Symmetric Turbulence Konzept (QSTK)…
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…
Critical gradient turbulence optimization toward a compact stellarator reactor concept
G. T. Roberg-Clark, G. G. Plunk, P. Xanthopoulos +3
Integrating turbulence into stellarator optimization is shown by targeting the onset for the ion-temperature-gradient mode, highlighting effects of parallel connection length, loca…
