Fixed-term contract: Magnetic Field Engineer

SOLEIL is the French national synchrotron facility, located on the Saclay Plateau near Paris. It is a multi-disciplinary instrument and research laboratory whose mission is to conduct research using synchrotron radiation, to develop cutting edge instrumentation on the beamlines, and to make these developments available to the scientific community. SOLEIL synchrotron, a unique tool for both academic research and industrial applications across a wide range of disciplines including physics, biology, chemistry etc., opened in 2008. It is used annually by thousands researchers from France and abroad. SOLEIL is based on a synchrotron source that is state-of-the-art both in terms of brilliance and stability. This large scale facility, a partner of the Université Paris Saclay, is a “publically owned” private company, founded by the CNRS and the CEA.

This position is open in the Magnets and Insertion Devices group in the Accelerators and Engineering Division.

The candidate for a fixed-term contract, will work in the Magnet and Insertions group made up of a group leader and her deputy, supervising four engineers and four technicians. The group is responsible for the accelerator magnets (linac, booster, beamlines, storage ring) and magnetic insertion devices (undulators or wigglers). The group is very involved in the preparation of SOLEIL II, in particular the development of the Booster magnets and the storage ring, and the development of a vibrating wire bench for magnet alignment.


You will carry out the construction and validation of different magnet prototypes through magnetic measurement and the development of a vibrating wire bench. For this mission, you will be led by an engineer expert in magnetic measurements and partially assisted by a technician.



Your activity will include several aspects:

  • Modelization
  • Vibrating wire validation
  • Dissemination


This position concerns a candidate with an engineering degree or a PhD, with knowledge in the fields of instrumentation and/or magnetism and/or electromagnetic radiation.
