Résumé

A tightly constructed rigid structure of a conductor winding and GFRP spacers in a coil case is an essential element for a superconducting magnet, that is to operate at a cryogenic temperature and sustain large magnetic forces. However, the contact pressures on the conductor, the spacers and the coil case, which are imposed in fabrication process, may be greatly reduced by relaxation at room temperature and by thermal contraction in the GFRP spacers during cool-down process. The authors therefore studied 61 kinds of commercial and test GFRPs and established a basis for suitable GFRP spacer material to be used in superconducting magnet windings.
