Abstract

The electrostatic turbulence in the edge plasma of the RFX reversed field pinch experiment has been studied using Langmuir probes and a homodyne reflectometer.The radial particle flux driven by electrostatic fluctuations has been measured in the region where a double E×B velocity shear layer occurs.It is found that almost 100% of the particle flux at the edge is driven by electrostatic fluctuations.The naturally occurring E×B velocity shear has been shown to be close to that required by the Biglari-Diamond-Terry criterion for turbulence radial decorrelation. © 1998 The American Physical Society.
