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 Döppler-enhanced microwave scattering by short-wavelength fluctuations entrained by large-scale turbulent flow in the equatorial plane of a tokamak.
