摘　　要：Divertor plasma properties for lower single-null （LSN） configuration in EAST, under a water-cooling graphite wall condition, are presented. A typical shot is selected for analyzing electron temperature, density and power flux at targets. Both higher electron density and lower electron temperature are found at the inboard target, compared to those at the outboard target. A higher power flux is also found to be at the outboard target because of in-out asymmetries for LSN-shaped discharge.Divertor plasma properties for lower single-null （LSN） configuration in EAST, under a water-cooling graphite wall condition, are presented.
