摘要：

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 x 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 x B velocity shear has been shown to be close to that required by the Biglari-Diamond-Terry criterion for turbulence radial decorrelation.
