The radial distribution of heat flux was obtained in the ion-drift side and electron-drift side of the SOL. By using thermocouples, the heat load on the graphite tiles of pump limiter head and its non-homogeneous poloidal distribution have been measured. The heat load on the limiter head and on the neutralizer plate of diverter was significantly reduced owing to the puffing at the head of plate. Some performances of the plasma also were improved.
