This project focuses on the conceptual designs and conductor studies for large superconducting detector magnets planned for the Future Circular Collider (FCC-ee) at CERN, the proposed successor to the Large Hadron Collider.
The work involves designing large superconducting solenoids that generate strong magnetic fields to help identify and measure particles produced in electron-positron collisions.
Responsibilities include analytical and finite-element studies of magnet windings, including thermal behavior, cryogenic cooling, and mechanical performance.
The role also includes supporting conductor R&D through studies and prototyping of low- and high-temperature superconductors. Additional tasks involve manufacturing, testing and characterising conductor samples for their superconducting, thermal, electrical, and mechanical properties.
Your responsibilities
* Conduct conceptual and finite-element studies of superconducting detector magnets, including cold mass geometry, thermal behaviour, cryogenic cooling, and mechanical performance.
* Support the design and optimisation of superconducting magnet systems for future particle detector applications.
* Participate in conductor R&D activities involving both low-temperature and high-temperature superconductors.
* Assist with conductor prototyping, demonstrator manufacturing, and experimental testing campaigns.
* Characterise conductor samples by evaluating their superconducting, thermal, electrical, and mechanical properties.
* This role includes team supervision responsibilities.
Your profile
* Background in superconductivity and superconducting technologies.
* Experience with superconducting magnet design and superconductor studies.
* Knowledge of materials science and characterisation techniques.
* Familiarity with experimental physics and cryogenic systems.
* Experience with analytical and finite-element analysis methods.
Skills
* Finite element analysis skills using commercial software such as Ansys and COMSOL.
* Capability to conduct experimental superconductivity campaigns, including cryogenic handling, operation of superconducting magnets, preparation of experimental setups, and execution of measurement techniques.
* Knowledge of superconducting conductor technologies, including mechanical properties and microstructural/morphological characterisation.
* Effective collaboration in multidisciplinary team environments.
* Independent work and autonomous management of tasks.
* Ability to present and document the outcome of studies
* Ability to supervise students or junior contributors.
* Spoken and written English, with a commitment to learn French.
