Short Wavelength Fluctuations and Electron Transport in TFTR

PDF Version Also Available for Download.

Description

Correlation between electron heat diffusivity and short wavelength (kri {approximately} 5) fluctuation amplitude was observed in the Tokamak Fusion Test Reactor (TFTR) tokamak in the core of enhanced reversed shear (ERS) plasmas [1]. These fluctuations propagate in the ion diamagnetic drift direction with wave number comparable to wpe/c. Further analysis of these data yields the ratios ce/ci and ce/De, and their values are consistent with the picture that the electron transport is mainly induced by the short wavelength fluctuations in the plasma core where the long wavelength (kri {approximately} 1) fluctuations are absent. Although there is not enough information to ... continued below

Although there is not enough information to identify these short wavelength modes, the values of ce is found to be comparable to theoretical predictions based on the current diffusive ballooning mode theory [2].
