Dummy coil development for the cable-in-conduit Nb/sub 3/Sn "outsert" coils of the 45 T hybrid magnet

Intermagnetics General Corporation, under a Phase I contract with the National High Magnetic Field Laboratory at Florida State University, is developing and demonstrating the manufacturing technology for the cable-in-conduit conductor (CICC) for the Nb/sub 3/Sn "outsert" coils of the 45 T hybrid magnet. This paper presents the technical development of cabling and sheathing of long length dummy CICC and the progress of manufacturing development for the full-diameter coil "A" using the dummy CICC. This will include coil stress analyses, winding technique, helium penetration ports, terminations, CIC conductor insulation, heat treatment and epoxy impregnation.<>
