      abstract     = {The JEDI Collaboration (Jülich Electric Dipole
                      Investigations) aims for a measurement of the electric
                      dipole moments (EDMs) of Deuterons and Protons at the COoler
                      SYnchrotron (COSY). To make this possible, a novel high
                      precision waveguide RF Wien filter was installed in COSY
                      inside a so-called low-beta section, to modulate the spin of
                      deuterons and protons. With this device the force of the
                      radial electric field iscanceled by the corresponding
                      vertical magnetic force. So it is possible to directly
                      manipulate the polarization vector of the particles without
                      introducing any beam oscillations. The RF Wien filter has
                      been designed tooperate at harmonics of the spin precession
                      frequency ranging from 0.6 to 1.7 MHz. For systematic
                      investigations of sources of false EDM signals, the
                      waveguide RF Wien filter can be rotated by 90 degrees around
                      the beamaxis. The results of several weeks of commissioning
                      experiments at COSY with the RF Wien filter, including
                      Lorentz force measurements, driven oscillations and the
                      resonant build-up of vertical polarization will be
                      presented. A series of test measurements similar to the the
                      upcoming first Deuteron EDM measurement were performed as
