Dynamics of L–H transition and I-phase in EAST, G.S. Xu et al 2014 Nucl. Fusion 54 103002, written by Dr. Guosheng Xu, the new head of Tokamak Division, and his colleagues, was selected as the “Highlight” of 2014 by Nuclear Fusion.
Dr. Xu and his colleagues are not alone in this “Highlight Group”. It is the fourth time that the ASIPP research result was appreciated by the international authority.(WU Sha reports)
Abstract of the Paper:
The turbulence and flows at the plasma edge during the L–I–H, L–I–L and single-step L–H transitions have been measured directly using two reciprocating Langmuir probe systems at the outer midplane with several newly designed probe arrays in the EAST superconducting tokamak. The E × B velocity, turbulence level and turbulent Reynolds stress at ~1 cm inside the separatrix ramp-up in the last ~20 ms preceding the single-step L–H transition, but remain nearly constant near the separatrix, indicating an increase in the radial gradients at the plasma edge...
