✦ Synopsis

The behawour of a sectton of multlhlamentary superconductor exposed to a pulsed longitudinal magnetic held/s invest/gated theoretically and experlrnentally and a new kmd of hlarnent couphng ortgmatmg from the twist has been found The reduced current dlstr/butlon, the rnagnettc moment, and the associated addtt/onal loss are evaluated Two crtttcal lengths of conductor corresponding to the beglnntng of saturation of the outer hlarnents and the total composite respectively are derived Experiments have been performed on Nb 7"1 mult/hlarnentary w/res and good aggreernent between theory and experiment/s found The extra losses are shown to be s/gn/hcant m certain magnet apphcat/ons A new tw/st scheme to reduce these losses/s proposed

Magnetic instabilities or flux jumps in multifilamentary superconducting composite conductors, exposed to a time-varying magnetic field perpendicular to the superconducting filaments, are studied. In particular, expressions for the stability limit field are determined for cases when the magnetic dif

Alternating current (ac) superconducting machines such as superconducting generators, transformers, or resistive current limiters need large-current-capacity conductors. These conductors are generally fabricated as multistrand cables stacked with multifilamentary NbTi superconductors whose current c
