Energy flux driven by electrostatic turbulence in the RFX edge plasma

The electron energy flux driven by electrostatic turbulence has been measured for the first time in the edge region of the RFX reversed field pinch experiment using triple Langmuir probes. The energy flux has been found to be almost entirely convective. The total energy loss due to electrostatic turbulence has been estimated to account for 30% of the overall transport losses
