摘　　要：Residual zonal flow level is calculated for tokamak plasmas in the neax-separatrix region of a diverted tokamak. A recently developed method is used to construct an analytic divertor tokamak configuration. It is shown that the residual zonal flow level becomes smaller but still keeps finite near the separatrix because the neoclassical polarisation mostly due to the trapped particles goes larger in this region.Residual zonal flow level is calculated for tokamak plasmas in the neax-separatrix region of a diverted tokamak.
