The use of superconductive wires instead of permanent magnets allows building undulators with shorter periods or higher magnetic fields. The photon wavelength can be tuned electrically without mechanically moving the magnets. The associatied field change, however, causes dynamic effects which are seen as a temporal drift of the beam orbit. The first systematic time resolved measurements of such drifts have been performed at ANKA, Forschungszentrum, Karlsruhe, Germany and will be presented in this thesis.
