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…

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…

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)…
