Ta, Ti and Hf effects on Nb${}_3$Sn high-field performance: temperature-dependent dopant occupancy and failure of Kramer extrapolation

Chiara Tarantini, Shreyas Balachandran, Steve M Heald +5

The increasing demand for improving the high-field (16-22 T) performance of Nb${}_3$Sn conductors requires a better understanding of the properties of modern wires much closer to irr…
