| dc.description | In modeling the properties of superconducting multi-filamentary strands, the filament twist pitch and the inter-filament transverse resistivity play a crucial role in the definition of the current transfer length. This affects the AC losses of NbTi strands, or the transport properties of Nb3Sn wires subject to a bending strain. Although the effect of filament twist pitch on the critical current of the strand has been studied, the value of the inter-filament resistance in Nb3Sn strands is still undefined. We have performed a direct measurement of the inter-filament transverse resistance within the cross-section of a Nb3Sn multi-filamentary strand from room temperature to 4.2K. Results have been compared to the inter-filament resistance of a sample on which the outer copper stabilization layer was removed by chemical etching, obtaining interesting indications on the preferential current paths within the wire cross section. | |
