摘要：

NbTi-based superconducting undulators (SCUs) have been developed and proven to increase the brightness by an order of magnitude at high X-ray energies at the ANL's Advanced Photon Source (APS). Nb3Sn has the potential to further enhance the performance of SCUs. A new project, aiming to fabricate a full-length, 3-m-long Nb3Sn SCU, compatible with the storage ring, has started at the APS. To develop the technology, three Nb3Sn short prototype magnets were fabricated and tested in liquid helium. These prototypes were used to incrementally improve the original design. The final short model magnet reached 100% of the short sample limit. The achieved current level in this magnet is 75% higher than what an NbTi wire can deliver.
