Abstract

Transport and mechanical properties of two Bi2212 superconducting coils under a large hoop stress were measured. The coils were 11-turn R&W type double pancake coils with an outer diameter of 280mm reinforced against electromagnetic stress by co-winding with an Ag-50%Cu or a Hastelloy X tape. They were measured in an external magnetic flux density of 10T and liquid Helium(4.2K). Critical current of the coil with the Ag-50%Cu reinforcement tape was 240A and its transport property was severely degraded by more than 0.4% deformation at I= 388A. The coil with the Hastelloy X tape with a critical current of 350A, showed good performance against an electromagnetic stress of 262MPa at I-500A and could repress deformation of the coil to within 0.22%.
