Accelerator Beam Physicist

SOLEIL is the French national synchrotron radiation center, located on the Saclay plateau near Paris. As a unique tool for academic research and industrial applications, SOLEIL is used every year by several thousand French and foreign researchers. This TGIR, “Très Grande Infrastructure de Recherche (Very Large Research Infrastructure)”, a partner of the University of Paris-Saclay, is constituted as a “civil” company founded jointly by the CNRS and the CEA.

To remain competitive in today's fast-paced international environment, and to develop scientific and technological solutions that meet society's major challenges, SOLEIL is embarking on a major upgrade of its accelerators and beamlines, called SOLEIL II.

The SOLEIL II project will enable experiments to be carried out up to ten thousand times faster, a thousand times more sensitive, with nanometer-scale resolution..., and thus make a decisive contribution to numerous societal challenges, in research into advanced materials, energy, and sustainable development, health and well-being, the environment...

I.Background and missions

The Accelerator physicist will work in the Accelerator Physics group of the Accelerators and Engineering Division. The group comprises 6 permanent members, physicists, supervising postdoctoral and doctoral fellows.

The main mission of the new recruit is to participate in the preparation of the major upgrade of SOLEIL accelerators, with a focus on linear and non-linear single-particle beam dynamics in the Booster and in the Storage Ring, construction follow-up and preparation of all codes and software tools to commission them and validate their performance and daily operation. He/she will also support the operation of SOLEIL and SOLEIL II, proposing innovative solutions to meet the demands of beamlines and promote new accelerator schemes. In this context, he/she may be called upon to take part in international programs and collaborations.

Profile Required

The present employment is open to candidates with a doctorate-level degree (PhD), with a specialization in Accelerator Physics, preferably with the knowledge of single-particle beam dynamics in a storage ring. The ideal candidate will have a proven track record of achievements and publications commensurate with their career level.

Any professional experiences on existing synchrotron installations shall be taken into account and valued.
