报告摘要:
Very high upper critical field and low anisotropy of iron-based superconductors (IBS) make them being particularly attractive for high-field applications, especially for the construction of nuclear magnetic resonance spectrometers, next-generation particle accelerators and ultra-high-field magnets.Conventional powder-in-tube method has been the most effective technique for fabricating IBS wires and tapes.Recently, significant progresses on the IBS wires have been made, in terms of both Jc enhancement and practical research. In this talk, the overview of the recent progress on Jc improvement and long wire fabrication will be provided.We also gives some advances relevant to practical applications, includingscalable process optimization, composite sheaths, multifilamentary fabrication, mechanical properties and superconductingjoints& coils
