Abstract
High-field applications which expose the superconductor to large time-varying magnetic fields, such as high performance generators and accelerator magnets, can benefit from a Nb3Sn conductor, with good high-field JC’s, having fully decoupled filaments. By adapting billet assembly techniques developed for the production of fine filament NbTi conductors to the fabrication of bronze-route Nb3Sn, a multifilament strand having unbridged filaments can be produced. The critical factors preventing filament bridging are the s/d (filament spacing/filament diameter) and the array quality, both of which can be precisely determined using these assembly techniques.
