Abstract
Edge plasmas, such as the tokamak scrape-off layer, exist as a consequ ence of a balance between cross field diffusion and parallel losses. T his circumstance is shown to lead to an unconventional form of the par allel ion transport laws under certain conditions. The cross field dif fusion, whether it is classical or anomalous, affects the parallel ion transport by modifying the parallel friction force between different ion species, which could be important for impurity retention in a toka mak divertor.
