Carolyn’s research interests focus on the processing of the high-temperature superconductor YBa2Cu3O7-x and specifically the creation of a low-resistance or superconducting joint between coated (RE)Ba2Cu3O7-x tapes.
One of the most promising commercially produced high temperature superconductors is (RE)Ba2Cu3O7-x in the film of a coated conductor on a Ni-alloy substrate. Its high Jc and mechanical strength make it promising for high energy physics applications. However, the ability to create low-cost superconducting joints has long been one of the barriers in the use of (RE)Ba2Cu3O7-x tapes for applications which require long lengths of superconductor, such as wound magnets. Current joining techniques require impractical processing conditions, such as high temperature, long-term annealing and yield low-resistance joints at best. Carolyn’s work focuses on the use of electric field processing in the creation of a high-quality joint, a technique which utilizes an electric field in lieu of high temperatures to allow for processing at room temperature conditions.
