The Possibility of Measuring Radial-Velocity Fluctuations in a Tokamak Plasma with the Aid of Enhanced Microwave-Scattering Diagnostics

We propose implementing the diagnostics of long-wavelength fluctuations of the radial velocity of tokamak plasma, which is based on Doppler-enhanced microwave scattering by short-wavelength fluctuations entrained by large-scale turbulent flow in the equatorial plane of a tokamak.
