High-m Kink/Tearing Modes in Cylindrical Geometry
J. W. Connor, R. J. Hastie, I. Pusztai +2
The global ideal kink equation, for cylindrical geometry and zero beta, is simplified in the high poloidal mode number limit and used to determine the tearing stability parameter,…
Equivalence of two different approaches to global gyrokinetic simulations
Felix I. Parra, Michael Barnes
A set of flux tube gyrokinetic equations that includes the effect of the spatial variation of the density, temperature and rotation gradients on the turbulence is derived. This new…
Dependence of intrinsic rotation reversals on collisionality in MAST
J. C. Hillesheim, F. I. Parra, M. Barnes +6
Tokamak plasmas rotate even without external injection of momentum. A Doppler backscattering system installed at MAST has allowed this intrinsic rotation to be studied in Ohmic L-m…
Intrinsic rotation in tokamaks: theory
Felix I. Parra, Michael Barnes
Self-consistent equations for intrinsic rotation in tokamaks with small poloidal magnetic field compared to the total magnetic field are derived. The model gives the mome…
