摘要: Electron temperature fluctuations have been investigated in the edge region of Caltech research tokamak [S. J. Zweben and R. W. Gould, Nucl. Fusion 25, 171 (1985)], an upper limit to this fluctuation level was found at Te/Te <~ 15%. This measurement, together with previous measurements density electric magnetic field fluctuations, allows a unique comparison heat transport resulting from three basic turbulent mechanisms: (1) flux particle microscopic fluctuations; (2) thermal conduction (3) fluctuations. The indicate that, regions, electron caused by measured turbulence-induced is comparable or greater than that associated significantly loss plasma turbulence be important energy mechanism regions.
