Abstract
This proposal will build a completely new collaboration between two groups working on superconductivity in Brazil and the UK. Teacher Hampshire's group in Durham is one of the world's leading groups working on the properties of superconductors in high magnetic fields. It houses state-of-the-art facilities to make measurements up to 15 T and has well-established access to international high-field facilities for making measurements up to 35 T in Grenoble. Teacher Zadorosny has pioneered the development of nanowire High Temperature Superconductors (HTS) using Solution Blow Spinning. For HTS materials to be widely used current fabrication costs must be reduced by about a facto r of 50! To about 1 $KA.m-1, which the nanowire fabrication route offers, while maintaining the high field performance currently only found in expensive quasi-epitaxial techniques. Hence, the exciting nanowire materials meet two important requirements: they are superconducting with typical dimensions of order 100 nm which makes them candidate materials for very high field applications (such as accelerator magnets and fusion energy applications); they are produced using well-established lost-cost nan fabric techniques. Unfortunately the nanowire HTS materials, do not yet carry high enough critical I current density for use in applications. This proposal brings together the pioneering fabrication expertise from the group in Brazil, with the established high field measurement expertise in the group from UK to identify whether the low critical current.
