摘要: Time and space resolved measurements of electrostatic Reynolds stress, radial electric field E(r), plasma rotations have been performed across the transition to improved Ohmic confinement in Hefei Tokamak-6M (HT-6M). The first experimental evidence correlation between enhanced stress gradient poloidal flow acceleration edge is presented. results indicate that turbulence-induced might be dominant mechanism create sheared which may further trigger transition.
