Study of low-frequency turbulence in the WT-1 tokamak plasma by CW FIR laser scattering

Abstract
An experimental study of low-frequency turbulence with wavelengths ranging from 2.5 to 0.4 cm in the WT-1 Tokamak is carried out by HCN laser scattering. It is found that the higher-frequency fluctuations are contained in the inner and the lower-frequency ones in the outer part of the plasma column.
