Magnetization and Flux Penetration of YBCO CORC Cable Segments at the Injection Fields of Accelerator Magnets

High-temperature-superconducting (HTS) cables are being considered for use in particle accelerator beam steering magnets. Knowledge of the magnetic properties of these HTS cables is needed for accelerator magnet design. Here, we present the results from a Hall probe magnetometer made for measuring the M-mu H-0 of short sections of superconducting cables in applied magnetic fields up to 12 T. The M-mu H-0 of a CORC cable was measured with field sweeps of +/- 4.5 T and also a -2- to 8-T loop. Relevant to a particle accelerator with an injection field of 1 T, the magnetization M-inj of the CORC cable was congruent to 900 kA/m and the penetration field B-p congruent to 1 T. The magnetization and penetration field of the cables are compared to tape from which the cables were wound, and the results are compared to NbTi and Nb3Sn conductors.
