This project is aimed at establishing the connections between local and global superconducting current-carrying abilities in magnesium diboride and high temperature superconducting tapes and wires. Local high-resolution magneto-optical imaging combined with transport current techniques will be employed. Super-current stream-lines and critical current density distributions will be quantitatively obtained from local magnetic flux behaviour. Pinpointing the connections is expected not only to promote production technology, but also to elucidate factors influencing the current-carrying ability in the tapes and wires.

该项目旨在建立二硼化镁和高温超导带材和导线的局部和全局超导载流能力之间的联系。将采用局部高分辨率磁光成像结合传输电流技术。从局部磁通量行为定量地得到超电流流线和临界电流密度分布。精确定位连接不仅有望促进生产技术，而且还将阐明影响带材和线材载流能力的因素。
