Abstract
AbstractThe effects of radial electric fields on neoclassical orbits in a tokamak are considered. It is shown that for high radial electric field shear, it is not possible to use local theory to describe neoclassical transport processes; this is due to a dramatic change of the particle orbit topology at a distance of the order of the particle orbit width. For the step‐like electrostatic potentials typical for the tokamak plasma periphery in the H‐mode, the trajectories of the particles can be either squeezed or expanded in the radial direction.
