Effect Of Exb Drift On Divertor Plasma Flows

Due to the influence of a sheared E×B drift affecting the inertia term in the plasma momentum equation a strong variation of the plasma pressure along the magnetic field lines can appear similar to experimental observations of the ‘‘detached divertor’’ regimes. The typical radial scale length of plasma parameter variation, such that the E×B drift becomes important, is of the order of the poloidal ion gyroradius.
