In the T-10 tokamak, the local fluctuations of poloidal electric field Epol and density ñe were simultaneously measured by heavy ion beam probe (HIBP) with 5-slit energy analyzer that allow us to estimate the turbulent particle flux and E × B rotation velocity in the gradient zone of plasma column (r/a = 0.8). It was shown that at the Ohmic heating (OH) stage of discharge, the outward flux is in the range of 2 × 1019 m−2 s−1, increasing at the ECRH stage by a factor of 1.5. At OH stage, the poloidal rotation velocity is about 4.5 km/s.
