Job Description
Your responsibilities
The High Field Magnets (HFM) Programme at CERN is driving the development of accelerator magnet technologies for a future energy-frontier circular collider.
In this context, CERN and its international partners are working to advance Nb₃Sn superconducting wires to the required performance, delivering new wire designs and pioneering nano-scale microstructural optimisation.
As an Applied Physicist, you will contribute to these activities by:
Designing studies and drawing conclusions to guide wire development in collaboration with manufacturers and research institutes.Performing quantitative image analysis of superconducting wires.Analysing phase transformations and diffusion processes during heat treatment.Assessing mechanical deformation of wires during cabling, and of cables under transverse stress, both experimentally and/or through modelling.Developing and conducting cryogenic electromagnetic tests of superconductors (e.g. critical current, magnetisation), and analysing the results.Your profile
Skills:
Essential skills:
Experience in image analysis.Background in materials science, including phase equilibria and deformation.Proficiency in scripting for data analysis and automation.Desirable skills:
Knowledge of applied superconductivity.Experience with finite element (FE) modelling.Experience in developing electrical tests.Spoken and written English or French, with a commitment to learn the basics of the other language.Eligibility criteria:
You are a national of a CERN Member or Associate Member State.You have a professional background in Physics, Materials Science (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.Additional Information

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.
