Examination of the Change in Intrinsic Rotation of the DIII-D Edge Pedestal Plasma During the L-H Transition

A previous analysis of an L-H transition in DIII-D\footnote{W.M. Stacey, Phys. Plasmas 20, 012509 (2013).} found that the radial particle pinch changed from outward to inward and the co-current edge intrinsic rotation dropped as the plasma went through the L-H transition. Two additional DIII-D discharges are now being examined in the late L-mode and early H-mode stages to determine if these features are characteristic of the L-H transition. A particle-momentum-energy balance analysis of the measured temperature, density, and rotation velocity is being performed to determine if the particle pinch reverses and the co-current intrinsic rotation due to ion orbit loss drops in the edge pedestal region during the L-H transition.
