Superconducting cable.


Scientists and engineers, using The VULCAN Engineering Diffractometer at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), are working with the U.S. ITER Project Office at ORNL, the Japanese Atomic Energy Agency and the ITER Organization to examine superconducting cables for ITER'S central solenoid magnet.

The central solenoid, a joint Japan-U.S. ITER responsibility, is on a tight schedule. The superconducting cables, supplied by Japan, cost more than $3,000 per meter. Improving the cable performance by reducing the degradation of the superconducting strands is important to staying on schedule and on budget. "We are working on an important problem that will have an immediate impact on science and technology on an international scale," said Ian Anderson, head of ORNL's Neutron Sciences directorate, which operates SNS.

The team of Japanese, U.S. and ITER Organization engineers discovered in late 2010 in a sample test that the superconducting cables making up the central solenoid...
