AbstractThe purpose of this study was to demonstrate the possibility of plasma current profile estimation by the correlation reflectometry. The method is based on the determination of the MHD mode oscillations localized in the vicinity of resonant magnetic surfaces by the correlative analysis of multichannel reflectometry signals.The described diagnostic technique allows one to make estimation of the location of different magnetic surfaces, which can provide information on the plasma current profile. Besides, the diagnostics gives frequency spectra and poloidal rotation velocities of the MHD perturbations on rational magnetic surfaces.
