Magnetization and design of multistrand superconducting conductors

Magnetization of cabled and braided samples which are long compared to their transposition lengths has been measured in a uniform magnetizing field directed at right angles to their widths. A separated double pancake with nonuniform windings was constructed to produce a suitably uniform radial field in which long coiled samples could be placed. Magnetization losses have also been measured in the ISA I magnet at BNL. Results are compared with theories which are due to Wilson[1] and, basically, Morgan.[2] Also, design optimization procedures have been defined for the use of multistrand conductors in magnet windings.
