Improved high-field superconductor technology is needed in High Energy Physics (HEP) to enable next generation machines with field performance in the range of 15-20 T. Short lengths of high temperature superconductors based on Bi-2223 and fabricated using demonstrated scalable processes have already achieved very promising superconductor critical current densities in this field range, approaching 1500 A/mm2 in a 12 T field at 4.2 K. However, BiSrCaCuO composites have not yet been made available with price-performance metrics appropriate for HEP; performance improvements are still required and costs must be significantly reduced. This project will investigate a novel process for producing very high performance BiSrCaCuO composite suited for HEP applications. Phase I will evaluate and develop a new long-length fabrication process that allows for new wire and cable designs. Ultimately, very high performance BiSrCaCuO material for HEP applications will be developed, with cross section current densities far greater than the minimum target of 250 A/mm2 in fields of 12 T at 4.2 K.
Commercial Applications and Other Benefits as described by the awardee: Advanced BiSrCaCuO materials should advance the state-of-the-art of High Energy Physics machines and also should enable or facilitate other government and commercial HTS applications that are dependent on performance and price.
