Joints between low temperature and high temperature superconducting materials for future magnet systems

The next generation of ultra-high field magnets will rely on the unique properties of high temperature superconducting (HTS) materials in the highest field regions, but will also use cheaper conventional low temperature superconducting (LTS) materials like NbTi and Nb3Sn for the lower field areas.  Magnets would be much simpler to design and build if superconducting joints could be made both between lengths of HTS materials and also between HTS and LTS materials, but there have been no reliable processing strategies yet designed to manufacture these HTS/LTS joints.  The student will work closely with our industrial partners Oxford Instruments and Siemens Healthineers to study the feasibility of making joints between state of the art commercial superconducting materials, to understand how to control unwanted reactions at the joint interfaces and to measure the performance of prototype joints at high currents and in high magnetic fields. There will be opportunities for the student to spend time in the partner laboratories near Oxford, and to become an expert in the correlation of microstructure with superconducting properties of the materials critical for future magnet designs.
