There are 7 Scientific Poles: Nuclear Physics, High Energy Physics, Astroparticles Astrophysics and Cosmology, Energy and Environment, Health Physics, Theoretical Physics and Accelerator Physics.

These scientific poles gather staff carrying out research activities and, in very specific cases, by technical staff whose activities are linked in a specific and lasting manner to the field concerned. This division into 7 scientific poles from the many themes within IJCLab is the result of a balance which takes into account both the grouping of projects and teams working on identical or related themes, thematic developments planned in the short / medium term, the existence of synergy in terms of working methods or the specific nature of the national and international contacts (collaborators, partners).

These poles are are structured into research teams and are headed by an Associate Scientific Director (DSA):

The work of these teams is carried out not only within their pole, but also in a more transverse way, in connection with the other scientific poles, the engineering pole and / or the IJCLab platforms.

Exchanges take place regularly within the Directoire which gathers the Direction of the laboratory, the Technical Director (in charge of the Engineering Pole) and the Associate Scientific Directors (in charge of the Scientific Poles) in order to perform the management of the laboratory.
