The Trials and Tribulations of Fabricating the Pipe for the “Rope in a Pipe” Nb3Sn Superconductor
A conductor using flowing supercritical helium as a coolant has been adopted for the superconducting magnet being built by the Airco-Westinghouse industrial team for the Large Coil Program (LCP) at Oak Ridge National Laboratory. This conductor utilizes the “rope in a pipe” concept in which a large number of superconducting Nb3Sn strands are formed into a cable and wrapped in a stainless steel jacket as shown in Fig. 1.
