Abstract

Correlation between electron heat diffusivity and short wavelength ( kρ i ∼5) fluctuation amplitude was observed in the TFTR tokamak in the core of ERS plasmas (Phys. Lett. A 236 (1997) 339). These fluctuations propagate in the ion diamagnetic drift direction with wave number comparable to ω pe / c. Further analysis of these data yields the ratios χ e / χ i and χ e / D e , 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 ( kρ i ∼1) fluctuations are absent. Although there is not enough information to identify these short wavelength modes, the values of χ e is found to be comparable to theoretical predictions based on the current diffusive ballooning mode theory (Plasma Phys. Control. Fusion 36 (1994) 279).
