1. New World Record for Superconducting Coil Performance PI: Gregory S. Boebinger, Director National High Magnetic Field Laboratory Supported by NSF (No. DMR-0084173), and State of Florida A collaboration of SuperPower, Inc. and the MagLab’s Division of Magnet Science and Technology and Applied Superconductivity Center Solenoid magnet of YBCO superconductor with a 9.5 mm diameter clear bore, a 82 mm winding diameter and a 52 mm winding height. A superconducting coil made from YBCO conductor, also known as ‘second generation’ conductor, was operated recently to a world record field of 26.8 tesla. The coil, fabricated by SuperPower Inc. in collaboration with the MagLab, was tested to a peak field of 7.8 T at a temperature of 4 K in the 19 T background field of the MagLab’s Large Bore Resistive Magnet. When used at very low temperatures, YBCO has upper critical magnetic fields and critical current densities that will allow superconducting magnets to operate at fields much higher than previously attainable with Nb-based superconductors, conceivably a factor of two higher. This small coil test is a first demonstration that YBCO processing has advanced to produce long lengths of high quality conductor. The availability of such high fields will dramatically increase the performance of all traditional applications of superconducting magnets, which include NMR, MRI and condensed matter physics research, as well as particle accelerators for medical and high energy physics applications. 2007

2. New Materials Leading to a Revolution in Superconducting Magnets PI: Gregory S. Boebinger, Director National High Magnetic Field Laboratory Supported by NSF (No. DMR-0084173), and State of Florida The Magnet Lab and SuperPower Inc. achieved a new world record of 26.8 tesla for a field created by a superconducting magnet using a test coil wound from YBCO-coated conductor wire. YBCO (Yttrium Barium Copper Oxide) is one of the high-temperature superconducting materials that were discovered in 1987 and are now thought to be on the verge of finding applications in electric power transmission, next-generation MRI (magnetic resonance imaging (MRI) magnets, and high-intensity superconducting magnets for research. The Magnet Lab is assessing the suitability of a material known as bismuth-2212, or Bi-2212, in round wire form, and YBCO-coated conductors in tape form to develop a 30-tesla superconducting magnet. On July 20, 2007, Magnet Lab researchers tested the small YBCO superconducting magnet by inserting it into the 200 mm bore of the lab’s unique 19-tesla wide-bore resistive magnet. Together the two magnets achieved 26.8 tesla, more than 1.8 tesla higher than the previous record field for a superconducting magnet. The availability of such high fields will dramatically increase the performance of all traditional applications of superconducting magnets, which include NMR, MRI and condensed matter physics research, as well as particle accelerators for medical and high energy physics applications.
