| Abstract: | Movable multielectrode probes are used in an experimental study of fluctuations in particle density and electric field, their
spectral and correlation characteristics, and the poloidal-radial distributions of fluctuation-induced drift fluxes in the
shadow of the diaphragm of the FT-2 tokamak. The spatial regions in which these fluxes are particularly intensive at different
stages of the discharge are determined. The part played by fluctuation-induced fluxes in the peripheral radial particle transport
is estimated and found to be substantial.
