Second stability region for gyrokinetics and the L-H transition
R. J. J. Mackenbach, A. Zocco, P. Helander
Using a simple circular tokamak geometry, we show the well-known `second stability region' of MHD-ballooning modes exists for linear gyrokinetics too -- whether electrostatic or el…

Available energy of plasmas with small fluctuations
P. Helander, R. J. J. Mackenbach
The available energy of a plasma is defined as the maximum amount by which the plasma energy can be lowered by volume-preserving rearrangements in phase space, a so-called Gardner…
