This chapter reports on the European Organization for Nuclear Research (CERN)-ELIN Nb 3 Sn dipole program. In this program a 1 m long model magnet was built, using Nb 3 Sn superconductor. The Nb 3 Sn magnet reached field levels of 9.5 T in the full dipole and 10.2 T in the magnetic mirror configuration in a 50 mm bore.
