Abstract
The structure of the electrostatic and magnetic turbulence changes in the proximity of the naturally occurring velocity shear layer in the TJ‐I tokamak [Nucl. Fusion 30, 717 (1990)]. Both a modification in the fluctuation levels and autocorrelation times of the Langmuir probe ion saturation current and a decorrelation in the broadband magnetic fluctuations, have been observed in the proximity of the shear layer location. However, no direct correlation between the sheared poloidal flows and turbulence characteristics has been established.Keywords
