Research

Small fluctuations in tokamak plasmas lead to turbulence, and turbulent eddies can very effectively transport heat from the hot core across confining magnetic field lines out to the cooler plasma edge. Predicting this phenomenon of turbulent-transport is essential for the development of fusion reactors. In order to improve predictive capability by testing and validating models of turbulent-transport, detailed measurements of fluctuations in high-performance, reactor relevant tokamak plasmas are required. Diagnostic techniques that allow for simultaneous measurements of fluctuations in plasma density, temperature, and flows in the core and edge of tokamaks and stellarators are presently being developed. In our group, we develop and use radiometers (electron cyclotron emission systems) for temperature fluctuations in tokamaks, reflectometers and interferometers for density fluctuations, as well as coupled radiometer/reflectometer instruments that allow for simultaneous measurement of temperature and density turbulence. With these new measurement capabilities we will improve our understanding of how turbulence is suppressed and how the turbulent-transport of particles, energy and momentum can be separated from one another. The new data from these measurements allow for stringent tests of turbulent-transport models. Presently, we are interested in determining what kinds of turbulent modes are dominant in different regions of operating space; specifically comparing small scale electron turbulence with larger scale ion turbulence, as part of ‘multi-channel transel validation efforts’. Close collaboration between experiment, theory and simulation is a key aspect of this work.
