Advancements in Superconducting Undulator Technology for Enhanced LCLS-II Performance

DESCRIPTION

This review discusses the potential of superconducting undulators (SCUs) to significantly enhance the performance of LCLS-II and future particle accelerators. With a proposal for 18 months of R&D, we aim to explore innovative engineering approaches and technologies to meet LCLS-II performance requirements. Collaborating with leading laboratories (ANL and LBNL), we hope to impact undulator design and support future expansion, even if implementation for LCLS-II proves too late. Our initiative promises dramatic improvements in free electron laser capabilities.

  1. Summary Paul Emma (SLAC) Superconducting Undulator R&D Review Jan. 31, 2014

  2. SCUs Can Have Dramatic Impact on LCLS-II 1.2 - 4.0 keV Self-Seeded (SS) PM In-Vac NbTi Nb3Sn 65 m g = 7.5 mm ge = 0.45 mm Ipk = 1 kA sE = 500 keV b = 15 m lu = 27.5 mm, 24.8 mm, 20.3 mm, 18.7 mm (4 GeV)

  3. Total Cost Estimate (ANL & LBNL) = 3.1 M$ No contingency added

  4. Summary • SCUs in LCLS-II, or future machines, can make a truly dramatic improvement in performance • LCLS-II performance requirements present an opportunity to take the next big step in FEL design • We propose 18 months of R&D to advance this technology, hoping to impact the LCLS-II design • The plan includes two engineering approaches and two technologiesin order to more fully explore options • We collaborate with very experienced labs (ANL & LBNL) • If too late for LCLS-II, this new technology can still support future (expansion) undulators for LCLS-II, or for any machine • Thanks for your attention and advice
