PROGRESS IN THE MANUFACTURE OF THE CABLE-IN-CONDUIT NB3SN OUTSERT COILS FOR THE 45-TESLA HYBRID MAGNET

The 45 Tesla Hybrid Magnet is being built in a collaborative effort be tween the National High Magnetic Field Laboratory at Florida State Uni versity and the Francis Bitter National Magnet Laboratory at the Massa chusetts Institute of Technology. The Hybrid Magnet combines a resisti ve insert magnet with two Nb3Sn and one NbTi superconducting cable-in- conduit outsert coll to produce the required field on axis. The Nb3Sn outsert coils are being built at Intermagnetics General Corporation un der contract with FSU. A design summary for the entire 100 MJ outsert magnet is presented. The design criteria and manufacturing status for the two Nb3Sn outsert coils are described.
