Company description

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 recognised as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams that are used by thousands of scientists each year for experiments in 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 is in charge of the main photon sources: the undulators. These systems are typically built with a large number of permanent magnets which needs to be precisely characterized, sorted and tuned.Integrals of magnetic fields can be measured with moving wires and coils. Combining field integral measurements at many angles allows to compute the magnetic field using tomographic reconstruction. The obtained field maps would allow to better model the permanent magnet blocks used for undulator construction. The internal inhomogeneities in these blocks, as well as the spread of their magnetic moments, is a major cause of the undulator magnetic errors which needs to be corrected by a long shimming process.

The student will first commission a dedicated magnetic field tomograph and implement the reconstruction algorithm. He/she will then develop magnetic models of permanent magnets which include internal inhomogeneities. These models should allow fast computations of the magnetic field at many points, using for instance boundary elements (i.e. Green’s functions) and the Fast Multipole Method. Models based on Artificial Intelligence (AI) will also be considered.

The field models will be used for building a digital twin of an undulator assembly. Optimization methods and AI will be applied to the undulator model for improving the magnetic field corrections and the reducing the construction time.
