Manufacturing of superconducting cable for the LHC-Key technology and statistical analysis

Manufacturing of superconducting cable for the LHC main dipole magnet is in progress at The Furukawa Electric Co., Ltd. (here after referred to as "FEC"). Fabrication technology of Rutherford type cable for accelerator magnets has made a remarkable advance through development of the LHC Cable2 Key technology includes many different things such as multi-filament billet design, assembly, control of copper to superconductor ratio, optimization of thermo-mechanical heat treatment, drawing process, Sn-Ag coating and cabling. The well- balanced Cable2 with high quality was developed, and all of the electrical and mechanical performances met the specification requirements. (7 refs).
