Abstract

Mechanisms of the impurity transfer inside a tokamak separatrix have been studied. It is shown that poloidal rotation significantly influences the poloidal distribution of impurities. An analysis of the neoclassical component of the radial impurity flux showed that this fraction is described by an expression that is more complicated than the standard neoclassical variant.
