The outsert coils of the Series-Connected Hybrid magnets for the National High Magnetic Field Laboratory and Helmholtz Zentrum Berlin each contain approximately 4000 kg of Nb3Sn/Cu cable-in-conduit conductor (CICC). There are three different sizes of CICC that grades the amount of superconductor. Significant progress has been made in all aspects of the CICC fabrication. The Nb3Sn strand, consisting of high J\rm CRRP Nb3Sn, and conduit, composed of 316 LN with critical chemistry modifications, have been manufactured and quality control measurements made. The additional service to create the ten lengths of superconducting and three lengths of prototype, multi-stage twisted Cu cable is also complete. Jacketing of the cables has successfully been carried out at a new facility (subset of ICAS) for the insertion and compaction of fusion technology CICC using a weld and pull method. Fabrication processes and quality controls have been developed through a collaborative effort between the NHMFL, HZB, Criotec Impianti, and ENEA Superconductivity Division. © 2011 IEEE.
