Tracking Turbulence in a Tokomak

Caption: ECE-Imaging and the new diagnostic, MIR, sample overlapping regions of the tokamak plasma and produce 2D images of turbulence and fluctuations. ECE-Imaging measures the radiation temperature of electrons orbiting around magnetic field lines, while MIR detects changes in the electron density. In the series of frames shown, an instability associated with the formation of internal magnetic islands can be seen rotating through the diagnostic field of view.
