      abstract     = {In high temperature fusion plasmas the transport of energy
                      and particles is commonly believed to be driven by
                      turbulence. Turbulence quantities as correlation length and
                      decorrelation time are important for the confinement
                      properties of a plasma. Besides other diagnostics,
                      correlation reflectometry has proven to be a suitable tool
                      for the measurement of turbulence properties. At the medium
                      sized Toroidal EXperiment for Technical Oriented Research
                      (TEXTOR) the existing correlation reflectometry has been
                      recently upgraded. A new reflectometer based on a microwave
                      synthesizer has been developed and installed for the
                      investigation of turbulence properties in a fusion plasma.
                      Together with the existing reflectometer the measurement of
                      radial correlation length and decorrelation time becomes
                      available. Both reflectometers are computer controlled and
                      allow to program individual frequency sequences and the
                      duration of each frequency step. With the existing poloidal
                      antenna array at θ=0° and on top of the vacuum vessel, the
                      system allows the measurement of radial correlation and
                      poloidal correlations at the same time. First experiments
                      have been performed and the results on the radial
                      correlation length of density fluctuations in a fusion
                      plasma are presented.},
