The SC magnet program at Fermilab has a long history of successful development of accelerator magnets based on NbTi superconductor starting from the Tevatron main ring and two interaction regions for CDF and D0, then dipole magnets for SSC and most recently, quadrupoles for the LHC Interaction Regions (IR). During past decade the magnet R&D program has focused on the new generation accelerator magnet technology based on Nb3Sn superconductor. This program started in 1998 as a platform for developing accelerator quality 10-12 T arc dipoles for a Very Large Hadron Collider (VLHC). In 2003, the emphasis was shifted to support the US-LARP initiative for Nb3Sn quadrupoles for a future LHC IR upgrade. Along the way we have contributed to several advances in Nb3Sn accelerator magnet technology. The most important breakthroughs made at Fermilab include the development and demonstration of high-performance Nb3Sn strand and cables, reliable and reproducible production-ready short and long coil fabrication technology, accelerator quality mechanical structures and coil pre-load techniques. While to date, there are no Nb3Sn magnets in operation in any HEP accelerator, the abovementioned advances in technology make it possible for the first time to seriously consider such magnets in any present or future accelerator. This talk will summarize the main results of Nb3Sn accelerator magnet R&D at Fermilab and discuss some possible applications of this technology in LHC and Muon Collider.
