Fundamental Studies for High Temperature Superconductor Conductor Technology
Abstract
Research on state-of-the-art conductor forms of Coated Conductors made from the superconducting material, YBa2Cu3O(x), has been performed. The principal results obtained are: (1) Misoriented substrate grains control the critical current performance of today's good conductor prototypes; (2) Magneto-optical imaging is a good means of studying the current flow barriers in such conductors; (3) Low angle grain boundary properties are of great importance to the percolation of current through a polycrystalline coated conductor; (4) Buffer layer microstructures control the way that epitaxy is built up from substrate to YBa2Cu3O(x) overlayer. The work has been carried out in collaboration with groups at AFRL, ORNL and industry.
