Title: Electron energy transport inferences from modulated electron cyclotron heating in DIII-D

Abstract

Electron thermal energy transport in high-temperature plasmas is poorly understood. A useful characterization of the transport as energy flux versus temperature gradient may be obtained for a modest range of fluxes and gradients about an equilibrium by using modulated electron cyclotron heating. The transport is rapid and stiff (high {chi}{sub inc}) at the outside, becoming slower and more diffusive toward the center.
