The 16 T magnet designs proposed for future energy-frontier circular colliders demand Nb3Sn superconducting wires with performance exceeding the current state of the art. This has driven intense research worldwide, resulting in exciting innovations including ‘internal oxidation’ for nano-scale optimisation of superconductor microstructures, but many challenges remain. In the context of the High Field Magnets (HFM) programme, CERN is working to develop and characterise novel Nb3Sn wires, in collaboration with manufacturers and research partners, and to qualify and cable them for use in model magnets.
This project contributes to the characterisation and optimisation of wire designs by:
• Designing studies and extracting conclusions to guide wire development collaborations with manufacturers and research institutes;
• Performing electron microscopy and quantitative image analysis of superconducting wires • Analysing phase transformations and diffusion during heat treatment;
• Assessing mechanical deformation characteristics of wires on rolling and cabling in relation to their design, experimentally and/or by modelling;
• Performing superconducting characterisation (critical current, magnetisation), and analysing the results.

What we offer
About us
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world’s largest and most complex scientific instruments, they study the basic constituents of matter – fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
