SUPERCONDUCTING WIRE AND CABLE FOR RHIC

The superconducting dipole and quadrupole magnets in the RHIC accelera tor ring are to be fabricated from 30-strand superconducting cable. Th e RHIC wire has a diameter of 0.65 mm, copper-to-superconductor ratio of 2.25, filament diameter of 6 mum and high critical current density. Primary emphasis during manufacturing has been on uniformity of mater ials, processes and performance. Near final results are presented on a production program which has extended over two years. Measured parame ters are described which are important for design of superconducting a ccelerator magnets.
