Improvement of critical current density in MgB2 wires and tapes and Y-Ba-Cu-O coated conductors

超导线材和带材技术已成为21世纪最重要的基础工程技术之一，它可以在电力、能源、机械、交通和环境等领域创造技术创新和提高生活质量。该计划的目的是通过使用新型纳米前驱体粉末开发二硼化镁超导体和YBCO涂层导体。掺杂纳米级粉末的超导带材有望显示出磁通钉扎性能的增强。预期的结果是能够以低成本生产具有高性能的新一代超导体。

The technology of superconducting wires and tapes has emerged as one of the most important basic engineering technologies, which can create technical innovation and improvement in the quality of life in the fields of electric power, energy, machinery, transportation and the environment in the 21st century. The aim of the proposed program is to develop magnesium diboride superconductor and YBCO coated conductors by using novel nano-precursor powders. Superconducting tapes doped with nano-sized powders are expected to show enhancement in flux pinning properties. The expected outcome is the capability to produce a new generation of superconductors having high performance at low cost.
