Abstract

The influence of plasma flow inhomogeneity on the magnetic surface, which is driven by anisotropic hot ions, on the micro-turbulence of the low/negative magnetic shear tokamak is investigated. It is found that the poloidal inhomogeneity is effective in suppressing the current-diffusive ballooning mode turbulence which has a large nonlinear growth rate. This new mechanism of turbulence suppression provides the model of improved confinement associated with the reversed magnetic shear.
