![]() Share the responsibility for the conductor qualification: Alex Vostner, Carlo Sborchia (F4E) and Arnaud Devred, Leader of the ITER Superconductor Section. After the successful test of the fourth European sample EUTF4 in June 2009, F4E has signed a first contract for the supply of more than 58 tons of niobium-tin (Nb3Sn) strand for the TF conductors with Oxford Superconducting Technology this August. The quantity is equivalent to about 60% of the total European Nb3Sn contribution, and with a volume of approximately 40 Million Euro this contract represents one of the largest F4E has placed so far for the ITER project. And there is more good news: This week, the EUTF5 sample made of Nb3Sn strand produced by Bruker EAS in Germany completed 1,000 load cycles with a final current sharing temperature (Tcs) above 6 K, thus meeting ITER's TF conductor design criteria of 5.7 K. << return to Newsline #101 |
