Applied Physicist - Materials Science (TE-MSC-LSC-2023-79-GRAP)

  • Full-time

Job Description

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.

Who we are looking for

    Eligibility criteria:

    • You are a national of a CERN Member or Associate Member State.
    • You have a professional background in 'Materials science, Condensed Matter Physics (or a related field) and have either:
      • a Master's degree with 2 to 6 years of post-graduation professional experience;
      • or a PhD with no more than 3 years of post-graduation professional experience.
    • You have never had a CERN fellow or graduate contract before.

    Skills and/or knowledge

    • SEM, image analysis, materials science (phase equilibria, deformation of metals/alloys), and scripting (data analysis);
    • Knowledge of applied superconductivity preferred, FEM modelling an advantage;
    • You should have a working knowledge of English or French.

    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.

    We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.
