Abstract

In this paper the results of the investigation of the edge turbulence performed in RFX by a set of Langmuir probes and a homodyne reflectometer are reported. The electrostatic turbulence exhibits large fluctuation amplitude and broad band features in frequency and wavenumber. The effect of the spontaneous E×B velocity shear layer observed at the edge is addressed in order to identify decorrelation effects on the turbulence. Similarities with tokamaks and stellarators are discussed.
