Abstract
High spatial resolution measurements of the electrostatic Reynolds stress, radial electric field and poloidal phase velocity of fluctuations in the ed ge region of the HT-6M tokamak are carried out. The Reynolds stress shows a radial gradient in proximity to the poloidal velocity shear. A comparison of the profiles between the Reynolds stress gradient and the poloidal veloc ity damping reveals some similarity in their magnitude and radial structure . These facts suggest that the turbulence-induced Reynolds stress may play a significant role in generating the poloidal how in the plasma edge region .
