Resonant Excitation of Shear Alfv\'en Perturbations by Trapped Energetic Ions in a Tokamak (2009)
Abel, I. G., Breizman, B. N., Sharapov, S. E., Contributors, JET-EFDA
A new analytic expression is derived for the resonant drive of high n Alfvenic modes by particles accelerated to high energy by Ion Cyclotron Resonance Heating. This derivation includes finite orbit...
Barnes, M., Abel, I. G., Dorland, W., Ernst, D. R., Hammett, G. W., Ricci, P., ...
A set of key properties for an ideal dissipation scheme in gyrokinetic simulations is proposed, and implementation of a model collision operator satisfying these properties is described. This...
Linearized model Fokker-Planck collision operators for gyrokinetic simulations. I. Theory (2008)
Abel, I. G., Barnes, M., Cowley, S. C., Dorland, W., Schekochihin, A. A.
A new analytically and numerically manageable model collision operator is developed specifically for turbulence simulations. The like-particle collision operator includes both pitch-angle scattering...
