Superconductor test successful

A prototype Nb3Sn sample of the Toroidal Field (TF) Coil conductor has been successfully tested in the Sultan high field test facility. The sample was fabricated for the ITER Organization by CRPP/PSI using conductor provided by the United States DA. Two cable configurations were tested in the two strands of the sample, the TF reference and a US derived configuration. At 70kA and 11.8T maximum field, the TF reference conductor achieved about 7K after 200 charging cycles and the other strand 0.7K less. The strand was manufactured by Oxford Superconductor Technologies following the internal tin route process.
