Abstract

CERN has designed and manufactured the first 1.7-m-long fully operational ReBCO CORC cable-in-conduit conductor. This CORC cable-in-conduit conductor is envisioned for use in large, high current and high energy magnets. The conductor has been successfully tested at 4.5 K/9 T and in 77 K/self-field. At 4.5 K, the CICC is fully superconducting up to the current limit of the test facility. The critical current of the conductor at 77 K is 12.3 to 13.0 kA with an n-value of 12 to 15, depending on ramp rate. The current distribution is observed to be homogeneous at both test temperatures. A resistance of 1.9 to 5.8 n \Omega is found for the joint terminals at 4.5 K in various magnetic fields and ramp rates, and 6.8 to 9.9 n\Omega at 77 K in self-field. The values found for the critical current and the resistance of the terminals at both 4.2 and 77 K are conform to the expectations based on a simulation model. The conductor underwent multiple thermal cycles no trace of degradation due to cabling, conduit assembly, joints and the high magnetic field tests was observed.
