Abstract
An important structural component of the Westinghouse Large Coil Program (LCP) superconducting magnet is the JBK-75 (modified A-286) stainless steel conductor sheath. This sheath is basically a welded pipe that encloses a bundle of superconducting cables. The JBK-75 conductor sheath also acts as a containment vessel for liquid helium. Stresses and strains produced on the conductor sheath result from a combination of magnetic loading, internal pressures and thermal loads.
