Effect of hydrogen content on the superconducting behaviour of commercial Nb3Sn wires
- 1. CNR-GNSM, Viale Benedetto XV, 5-16132 Genova
Description
Nb3Sn commercial wires (diameter 0.5 mm, 3700 filaments) have been hydrogen doped at various concentrations and the superconducting properties of these wires have been correlated to the hydrogen content x in Nb3SnH /SUB x/ . Here the results are presented which regard critical temperature and overall critical current density for applied fields from 9 T to 12 T at 4.2K and 6K for hydrogen content up to x = 0.310. The critical temperature trend shows a slight maximum at x approx. = 0.02, after which it decays abruptly. Also the critical overall current density at same hydrogen concentration is higher than that of unhydrogenated samples at 4.2 K and is comparable or better at 6 K. The resulting dJ /SUB ov/ /dB shows a good behaviour in the studied field range
