Abstract :
The superconducting cable-in-conduit conductor (CICC) for the TF Coil Insert (TFCI) consists of the cable (1152 superconducting Nb3Sn strands of 0.81 mm diameter) jacketed by welded titanium conduit. All superconducting strands are covered by Cr layer of near 2.5 μm thickness and cabled in five stages. The sub-cables and the full cable are wrapped by the thin SS tape. The manufacturing procedure was carried out for a jacketing of cable by the tubes of titanium (2.0 mm thickness). This paper presents the description of the conductor manufacturing process. cabling, welding of conduit, insertion of cable, compaction, winding of coil and QA procedure. The coil of TFCI was made of the superconducting conductor successfully.
