Reduction of electrostatic turbulence in a quasi-helically symmetric stellarator via critical gradient optimization
G. T. Roberg-Clark, P. Xanthopoulos, G. G. Plunk
We present a stellarator configuration optimized for a large threshold (``critical gradient'') for the onset of the ion temperature gradient (ITG) driven mode, which achieves the l…

Coarse-grained gyrokinetics for the critical ion temperature gradient in stellarators
G. T. Roberg-Clark, G. G. Plunk, P. Xanthopoulos
We present a modified gyrokinetic theory to predict the critical gradient that determines the linear onset of the ion temperature gradient (ITG) mode in stellarator plasmas. A coar…
