Abstract
Commercial NbTi and Nb3Sn multifilamentary superconducting wire is becoming increasing important for use in research and commercial magnet systems. In both materials the temperature dependence of Jcplays a major role in the determination of magnet system operating parameters and design stability margins. We report here critical current density measurements as a function of temperature from 4.2 to 19 K and of applied magnetic field upto 8 T for multifilamentary Nb3Sn wire and for 2 alloys of NbTi superconducting wire. From this data [\partial J_{c}(H_{a})/\partialT] and[\partialH_{c2}/\partialT]T=T_{c}can be obtained and stability criteria and other superconducting parameters of the wires may be extracted.Keywords
