    Description
    To achieve the luminosity requirements of CLIC at the collision point, damping rings equipped with superconducting wiggler magnets should be used to produce ultra-low emittance with high bunch charge. The baseline design foresees 52 Nb-Ti superconducting wigglers in each of the two damping rings of CLIC. A full scale Nb-Ti wiggler has been built at BINP, in the frame of BINP/KIT/CERN collaboration and is foreseen to be installed in the ANKA storage ring to test the wiggler system with beam. Although Nb-Ti wigglers meet the specifications for CLIC damping rings, the more challenging Nb3Sn technology could be used to increase the magnetic flux density amplitude in the gap and reduce the total length of wigglers in the damping rings. To test the Nb3Sn technology, a small wiggler prototype is under design and will be built and tested at CERN. In this seminar, the status of the Nb-Ti wiggler magnet and the Nb3Sn prototype will be presented.
