Variations in the characteristics of the superconducting wire used for the ISR superconducting high-luminosity insertion

A total of 30000 meters of NbTi solid multifilamentary superconductor, I/sub c/ approximately 2500 A at 6 T, was tested. For each stretch of wire received, measurements were made to check if the wire met the specifications. The specification and the measuring set-up are described. Systematic measure...

Sumario:A total of 30000 meters of NbTi solid multifilamentary superconductor, I/sub c/ approximately 2500 A at 6 T, was tested. For each stretch of wire received, measurements were made to check if the wire met the specifications. The specification and the measuring set-up are described. Systematic measurements of the critical currents, Cu:SC ratio, Ti content and wire size are discussed. A strong variation in the critical current could be correlated to a strong variation in the Ti content. (4 refs).
