TI - Progress on the Nb₃Sn Superconducting Undulator Development at the Advanced Photon Source J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - The Nb₃Sn-based superconducting undulator (SCU) is a strong candidate to outperform its well-establish counterparts, such as the NbTi-based SCU and cryogenically cooled permanent magnet undulators, over a wide range of undulator period lengths: 10 mm or larger. Thus, the Advanced Photon Source (APS) at Argonne National Laboratory has initiated a project, in collaboration with Fermilab and Berkeley Lab, aiming to establish a robust technology for the fabrication of a Nb₃Sn SCU and validate its operational and radiation performance on the APS storage ring. To accomplish this, first, modeling-driven optimizations were employed to address the magnetic and mechanical design of the undulator magnets, and a series of 4.5-period prototypes subsequently confirmed the design specifications. Then, these short prototypes were successfully scaled to 0.5-m-long magnets, confirming the maximum design field of 1.2 T that is at least 20% higher than a NbTi version with the same gap and period length (9.5 mm and 18 mm, respectively). Fabrication of the final 1.1-m-long magnets is currently underway. Further details will be presented. PB - JACoW Publishing CP - Geneva, Switzerland ER -
