Title: Experimental studies of plasma fluctuations using electron cyclotron emission on ATF (Advanced Toroidal Facility) and TEXT (Texas Experimental Tokamak)

Abstract

The great stumbling block in the quest for fusion power using magnetic confinement devices is anomalous transport. It is conjectured that turbulent plasma fluctuations may be responsible for the degraded energy confinement observed in experiments. There exists a clear need for more detailed experimental studies of plasma microturbulence. We have started a set of experiments to measure electron temperature and density fluctuations using electron cyclotron emission (ECE). The ECE systems will employ auto-correlation and cross-correlation techniques to measure radiation from the Advanced Toroidal Facility at Oak Ridge National Laboratory (ORNL) and also from the Texas Experimental Tokamak (TEXT) at the University of Texas. This set of experiments on a stellerator and a tokamak will allow a unique comparative study of the fluctuation physics in the two different magnetic configurations. This work is in support of the United States Department of Energy Tokamak Transport Initiative and involves a collaborative effort between Auburn University, Georgia Institute of Technology, the University of Texas at Austin and ORNL. 3 refs.
