    "abstract": "We report the first experimental observation of stationary zonal flows in the\npedestal region of the H-mode plasma in the H-1 toroidal heliac. Strong peaks\nin E_r shear mark the top and foot of the density pedestal. Strong m=n=0\nlow-frequency (f \u003c 0.6 kHz) zonal flows are observed in regions of increased\nE_r, suggesting substantial contribution of zonal flows to the spatial\nmodulation of E_r radial profiles. Radial localization of zonal flows is\ncorrelated with a region of zero magnetic shear and low-order (7/5) rational\nsurfaces.",
