Energetic bounds on gyrokinetic instabilities. Part I: Fundamentals
P. Helander, G. G. Plunk
Upper bounds on the growth of free energy in gyrokinetics are derived. These bounds apply to all local gyrokinetic instabilities in the geometry of a flux tube, i.e. a slender volu…

Electrostatic potential variation on the flux surface and its impact on impurity transport
J. M. García-Regaña, C. D. Beidler, Y. Turkin +5
The particle transport of impurities in magnetically confined plasmas under some conditions does not find, neither quantitatively nor qualitatively, a satisfactory theory-based exp…

Less constrained omnigeneous stellarators
Felix I. Parra, Ivan Calvo, Per Helander +1
A stellarator is said to be omnigeneous if all particles have vanishing average radial drifts. In omnigeneous stellarators, particles are perfectly confined in the absence of turbu…
