Global effects on neoclassical transport in the pedestal with impurities

, 2016
We present a numerical study of collisional transport in a tokamak pedestal in the presence of non-trace impurities, using the radially global δf neoclassical solver Perfect (Landreman et al 2014 Plasma Phys. Control. Fusion 56 045005).

Large orbit neoclassical transport

Physics of Plasmas, 1997
Neoclassical transport in the presence of large ion orbits is investigated. The study is motivated by the recent experimental results that ion thermal transport levels in enhanced confinement tokamak plasmas fall below the “irreducible minimum level” predicted by standard neoclassical theory.

Impurity transport and neoclassical predictions

Plasma Physics and Controlled Fusion, 1991
The authors present a brief review of collisional (classical and neoclassical) and anomalous transport. Particular emphasis is devoted to the question of charge independence of the anomalous transport coefficients and the combined action of anomalous and collisional transport.

Dynamics of enhanced neoclassical particle transport of tracer impurity ions in ion temperature gradient driven turbulence

, 2021
Tracer impurity transport in ion temperature gradient-driven (ITG) turbulence is investigated using a global full-f gyrokinetic simulation including kinetic electrons, bulk ions, and low to medium Z tracer impurities, where Z is the charge number.

Unified modeling of both resonant and non-resonant neoclassical transport under non-axisymmetric magnetic perturbations in tokamaks

Physics of Plasmas, 2019
A numerical model for neoclassical transport under nonaxisymmetric magnetic perturbations in low collisionality plasmas in tokamaks is developed. To take into account bounce-drift resonances and magnetic drift effects, a Fourier decomposition of the ...
