摘要：
Low-frequency (<2 MHz) plasma turbulence in the FT-2 tokamak is studied experimentally with the help of a technique based on the study of enhanced scattering and X- and O-reflectometry in the ohmic heating regime during current drive, in the transitional regime from current drive to lower hybrid heating, and during lower hybrid heating. The experimental results are analyzed and compared with the data from CO2-laser light scattering obtained in the same regimes. A characteristic size of the region in which small-scale turbulence is efficiently driven is determined.
