Permanent researcher / Head of the High Intensity Physics Group - LIDYL - H/F

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 Directorate for Fundamental Research (DRF), implemented on all civilian centers of the CEA, has as its main objective to undertake fundamental research in relation to the missions of the CEA in the fields of physics, chemistry and life sciences, in which its excellence is internationally recognized.

Description de l'unité

The Interactions, Dynamics and Lasers Laboratory (LIDYL), which is part of the CEA's Institut Rayonnement Matière de Saclay (IRAMIS) and which houses the ERL9000 CNRS-CEA, carries out fundamental research on laser-matter interaction in ultra-short pulse duration and Ultra-High Intensity (UHI) regimes. LIDYL hosts the cutting-edge ATTOLab-Orme (dedicated to ultrafast dynamics studies in the gas and solid phases at the femtosecond and attosecond time scales) and UHI100 (devoted to relativistic optics, radiation generation and particle acceleration studies) facilities. The latter is based on a 100TW class Titanium-Sapphire laser coupled to a new experimental area, the geometry and equipment of which have been optimized in the frame of the fitting out of the entirely new LIDYL laboratories implemented on the Orme des Merisiers site near Saclay in 2021. The state-of-the-art facility UHI100 will allow the use of two intense, synchronized laser beams with an ultra-high contrast. This configuration will expand the range of experimental investigations, for instance in the fields of relativistic optics on plasma mirrors or laser particle acceleration in dense and underdense-plasmas.

Job title

Permanent researcher / Head of the High Intensity Physics Group - LIDYL - H/F

Socio-professional category


Job description

The scientist recruited will be heading the LIDYL’s High Intensity Physics group, which brings together nearly ten researchers, technicians and students. As such, they will provide scientific leadership within the team and be in charge of the operation (including schedule) of the UHI100 facility. In conjunction with the other researchers in the group, they will carry out their own high-level experimental scientific program. The latter will make the best use of the UHI100 facility characteristics, without excluding the use of external experimental platforms. The selected candidate will actively build research projects in response to national and European calls for funding applications in order to ensure the sustainable funding of their scientific activity and keeping up the competitiveness of the UHI100 platform at the best international level. In this perspective, they should be able to forge links with the concerned national and international scientific communities, and possibly with various industrial players in the field of lasers, optics and photonics. They will ensure the best possible visibility of the research group within these communities. They will also work in close collaboration with the management of LIDYL and IRAMIS, both within the framework of the CEA missions, as well as on programs of mutual interest with academic partners, in particular the CNRS, the University of Paris-Saclay and the Institut Polytechnique de Paris, but also with industrial partners.


More specifically, the incumbent will:

- Ensure scientific leadership of LIDYL’s PHI group. They will promote interactions among the various scientific activities and technical achievements by stimulating discussions (including within the department, as for instance with the SLIC group in charge of lasers operation) and cooperation between researchers, to build a coherent scientific program.

- Optimize the operation of the UHI100 facility by organizing the operation schedule for the internal and external users.

- Develop an original, high-level experimental program in the field of Ultra High Intensity laser-matter interaction which exploits the performances of the UHI100 facility, as well as other cutting-edge laser facilities in France and abroad (Apollon, ELI, CoReLS, ...).

- Respond to national and international calls for applications in order to ensure sustainable funding of their scientific programs and operation of the facility. These resources will support UHI100 competitiveness at the best international level.

- Ensure the visibility of the group at an international level and estabish scientific collaborations and partnerships.

- Contribute to the achievement of CEA’s missions and in collaboration with other research organizations.

Applicant Profile

Required qualifications:

- The incumbent must have a solid experience on high-power laser facilities, and in particular on 100 TW class or equivalent level.

- They will have to master the physics of laser-matter interaction at ultra-high intensity.

- They should have demonstrated management skills and their ability to initiate international collaborative projects. Demonstrated experience in raising research funds based on competitive applications is also required.

- The candidate should have advanced communication skills to ensure the visibility of their scientific activity and of the group at the international scale. Fluency in English (spoken and written) is mandatory.

- They must be motivated to coordinate and defend the scientific and career interests of a diverse research team of about ten people, with various scientific and technical backgrounds.


Application/selection procedure:
The recruitment will be based on an open international competition.

Candidates must apply online via the CEA career website ( and by emailing a complete file to

The application file will contain: 

-   a CV;

-   a comprehensive record of professional achievements (publications, fellowships, awards, etc…) including a short description of the main personal accomplishments (conceptual, technical,… );

-   a cover letter highlighting the motivations for applying to this position;

-   a vision of the scientific program and required technological developments for the facility  over the next 5-10 years;

-   contact data of three professional references.


Application deadline: 08/31/2021 - 23:59 CEST.


A limited number of candidates will be invited for a panel interview in September-October 2021. Only these preselected candidates will be contacted.
