This result suggests that the transition is governed by the enhancement of the magnetic shear near the plasma edge, associated with the radial modification of the edge current-density profile.}, title = {Role of edge magnetic shear on the limiter H-mode transition of the JIPP T-IIU tokamak}, volume = {Vol.64}, year = {1990} }
