Description du poste

The European Synchrotron, the ESRF, is an international research centre based in Grenoble, France.

Through its innovative engineering, pioneering scientific vision, and a strong commitment from its 700 staff members, the ESRF is recognized as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams used by thousands of scientists annually across diverse fields such as biology, medicine, environmental sciences, cultural heritage, materials science, and physics.

Supported by 19 countries, the ESRF is an equal opportunity employer and encourages diversity.

The Insertion Devices and Magnets group manages the main photon sources: the undulators. These systems are built with numerous permanent magnets that require precise characterization, sorting, and tuning. Integral magnetic field measurements are conducted with moving wires and coils, and combining these measurements at multiple angles enables tomographic reconstruction of the magnetic field. This process produces field maps that help model the permanent magnet blocks used in undulator construction. Internal inhomogeneities and magnetic moment variations in these blocks cause magnetic errors in the undulators, which are corrected through extensive shimming.

The student will first commission a dedicated magnetic field tomograph and implement the reconstruction algorithm. Subsequently, they will develop magnetic models of the permanent magnets, incorporating internal inhomogeneities. These models should facilitate rapid magnetic field computations at numerous points, potentially using boundary elements (e.g., Green's functions) and the Fast Multipole Method. AI-based models will also be explored.

The field models will underpin the creation of a digital twin of an undulator assembly. Optimization techniques and AI will be employed to enhance magnetic field corrections and reduce construction time.
