A YEAR'S EXPERIENCE WITH A SUPERCONDUCTING UNDULATOR IN THE STORAGE RING ANKA *

In March 2005 a superconductive undulator was installed in ANKA and since that time has been in operation [1]. The cryogen-free superconducting undulator was warmed up for one day one year later for routine maintainance of the cryocoolers. The results of the first ever beam tests of a superconducting undulator in a storage ring are summarized in this paper including the obtained spectra and the measurements on the heat load from the beam. The values obtained are so promising that a new undulator with improved performance will be built for ANKA and installed in two years from now.
