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…

Energetic bounds on gyrokinetic instabilities. Part 4. Bounce-averaged electrons
P. J. Costello, G. G. Plunk
Upper bounds on the growth of instabilities in gyrokinetic systems have recently been derived by considering the optimal perturbations that maximise the growth of a chosen energy n…
