摘要：

The structure of the edge radial electric field Er inferred from the poloidal rotation velocity is compared with that of the particle and thermal transport barrier for H-mode plasmas in JFT-2M. Both Er and its gradient Err in the thermal transport barrier are found to become more negative at the L-H transition. On the other hand, Err is more positive outside of the separatrix. The shear of the radial electric field and poloidal rotation velocity in the H mode is localized within the order of an ion poloidal gyroradius near the separatrix, in the region of ion collisionality *i2040. © 1990 The American Physical Society.
