Investigation of GAM zonal flows near the pedestal region of H-mode on EAST tokamak

Investigation of GAM zonal flows near the pedestal region of H-mode on EAST tokamak

Geodesic acoustic mode (GAM) is the finite frequency counterpart of zonal flow in toroidal plasmas, which could be excited by and regulate turbulence. This article reports a stationary eigenmode GAM at the inner side of the edge radial electric field contributing to an extreme high confinement plasm...
