Drift kinetic theory of alpha transport by tokamak perturbations
Elizabeth A. Tolman, Peter J. Catto
Upcoming tokamak experiments fueled with deuterium and tritium are expected to have large alpha particle populations. Such experiments motivate new attention to the theory of alpha…
Non-linear neoclassical model for poloidal asymmetries in tokamak pedestals: diamagnetic and radial effects included
Silvia Espinosa, Peter J. Catto
Stronger impurity density in-out poloidal asymmetries than predicted by the most comprehensive neoclassical models have been measured in several tokamaks around the world during th…
Geometry and neoclassical theory in a quasi-isodynamic stellarator
Matt Landreman, Peter J Catto
We show that in perfectly quasi-isodynamic magnetic fields, which are generally non-quasisymmetric and which can approximate fields of experimental interest, neoclassical calculati…
Drift ordered short mean free path closure
Peter J. Catto, Andrei N. Simakov
The complete short mean free path description of magnetized plasma in the drift ordering has recently been derived. The results correct the previous expressions for the ion pressur…
