Show affiliationsThe correlation between O- and X-mode reflectometer signals is studied with a one- and two-dimensional reflectometer model in order to explore its feasibilities as a q-profile diagnostic. It was found that two-dimensional effects and finite fluctuation levels both decrease the O-X correlation. At very low fluctuation levels, which are usually present in the plasma core, there is a good possibility of determining the local magnetic field strength and use that as a constraint for the equilibrium reconstruction.
