摘要：
Performance verification of the Nb3Sn cable-in-conduit conductor (CICC) for the Series-Connected Hybrid magnets at the National High Magnetic Field Laboratory (NHMFL) and Helmholtz Centre Berlin is performed through short sample testing. The superconducting outsert coil consists of three CICC configurations, graded for the applied magnetic field. The CICC for the high field section of the coil is tested in the SULTAN facility at EPFL-CRPP. Measurements of the current sharing temperature at field current combinations comparable to what is expected in the magnet are made. Electromagnetic cycling is performed to investigate the Nb3Sn strand sensitivity to transverse loads. In addition, measurements of AC loss and pressure drop along the conductor are made and compared to thermal-hydraulic computations.
