Kl. Wong et al., SHORT-WAVELENGTH FLUCTUATIONS AND ELECTRON HEAT-CONDUCTIVITY IN ENHANCED REVERSED SHEAR PLASMAS, Physics letters. A, 236(4), 1997, pp. 339-344
Short wavelength fluctuations with k similar to omega(pe)/c and k rho
i similar to 5 are detected by microwave scattering in TFTR plasmas wi
th reversed magnetic shear. They propagate in the ion diamagnetic drif
t direction with a frequency below the ion diamagnetic drift frequency
in the frame of reference where E-r = 0. The variation of the fluctua
tion amplitude in the plasma core correlates with the variation of the
local electron heat conductivity, suggesting that these fluctuations
may be the cause of anomalous electron heat transport in these plasmas
