Niobium Titanium Superconductors with Improved Current Density Through the Use of Artificial Pinning Centers

人工钉住结构有望显著提高超导体的临界电流密度。我们建议：(1)构建和测试复合导体来完成数据库；(2)使用该数据库来测试现有的钉钉理论，并根据需要对其进行扩展，以表明在第二阶段实现临界电流密度增加一到两倍的可行性。选择用于完成数据库的复合材料可能具有在0到10T范围内产生的最高临界电流。

Artificial pinning structures promise dramatically increased critical current densities in superconductors. We propose: (1) construction and test of composite conductors to complete the database and (2) use of this database for the testing of existing pinning theories, expanding on them as necessary to indicate the feasibility of factor-or-two increases in critical current density to be achieved in Phase II. The composites chosen to complete the database may have the highest critical currents every produced in the 0 to 10T field range.
