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…

Tightening energetic bounds on linear gyrokinetic instabilities
P. J. Costello, G. G. Plunk
Bounding energetic growth of gyrokinetic instabilities is a complementary approach to linear instability analyses involving normal eigenmodes. Previous work has focused on upper bo…

Observation and characterisation of trapped electron modes in Wendelstein 7-X
A. Krämer-Flecken, J. H. E. Proll, G. Weir +17
In the past, quasi coherent modes were reported for nearly all tokamaks. The general definition describes modes as quasi coherent when the magnitude squared coherence is in the ran…
