DUMMY COIL DEVELOPMENT FOR THE CABLE-IN-CONDUIT NB3SN OUTSERT COILS OF THE 45T HYBRID MAGNET

Intermagnetics General Corporation, under a Phase I contract with the National High Magnetic Field Laboratory at Florida State University, i s developing and demonstrating the manufacturing technology for the ca ble-in-conduit conductor (CICC) for the Nb3Sn ''outsert'' coils of the 45T hybrid magnet. This paper presents the technical development of c abling and sheathing of long length dummy CICC and the progress of man ufacturing development for the full-diameter coil ''A'' using the dumm y CICC. This will include coil stress analyses, winding technique, Hel ium penetration ports, terminations, CIC conductor insulation, heat tr eatment and epoxy impregnation.
