Vacancy details

General information


The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.

The CEA is established in ten centers spread throughout France



Division description

The Basic Research Division conducts research at the highest international level in the fields of physics, chemistry, biology, and climate and environmental sciences, in direct relation to CEA's missions for Energy.

Description de l'unité

The missions of the Léon Brillouin Laboratory (LLB) are the development of its own research using neutron scattering, the construction, maintenance and operation of instruments (outstations) around different neutron sources in Europe, as well as training in neutron scattering techniques. The LLB is also working, with the French neutron community, on a project of compact neutron source using a gas pedal.
In this context, building, imagining and exploiting neutron beams to perform physics experiments is still a formidable challenge for the IRAMIS/LLB teams. These experiments are essential to "invent" the neutron diffraction of tomorrow

Job title

Researcher in quantum materials and in instrumental developments for compact neutron sources H/F

Socio-professional category


Job description

The New Frontiers in Quantum Materials (NFMQ) group, one of the two LLB scientific groups, is hiring a physicist to strengthen its activity in the field of quantum materials, and to take part in the instrumental developments specific to compact neutron sources. Indeed, the implementation of neutron scattering techniques in this field has specific requirements, related to the pulsed character of compact sources, compared to reactors. The recruited person will participate also in the development of innovative methods of data processing for pulsed sources. She will also manage collaborators and users on the laboratory’s outstations at ILL and PSI.

Her/his missions will therefore be as follows:

• Development of a research axis which takes advantage of neutron techniques, to study magneto-structural correlations in quantum materials (such as superconductors, frustrated or low-dimensional magnetic systems, multiferroics, molecular magnets, etc.), while opening up to other complementary techniques (magnetometry, X-ray scattering). This research will be based on the various European large scale facilities (neutrons, synchrotrons).

• Development and implementation of diffraction and spectroscopy techniques on compact neutron sources.

• Participation in the development of data processing softwares for time of flight sources.

• Reinforcement of projects with external collaborators in the fields related to quantum materials on the LLB outstations : SHARP +, SAM (ILL) and stations such as POLI at FRMII.

• Writing research projects and/or funding applications.
