The peak of poloidal flow in the electron diamagnetic direction suddenly appears near the plasma edge in H-mode. No critical normalized ion collisionality, nu star_ i, for the transition of L- to H-mode is observed. The size of the poloidal flow in H-mode has no dependence on poloidal gyro-radius.}, title = {Edge Poloidal Rotation Profiles of H-Mode Plasmas in the JFT-2M Tokamak}, year = {1991} }
