Within Irfu as part of the CEA missions, the Nuclear Physics Division (DPhN) is leading experimental and theoretical fundamental research in nuclear physics. DPhN is also applying its knowledge and expertise to measurements and modeling related to society topics involving nuclear energy, to the design as well as to the dismantling of facilities.
The strong interaction, the main actor in nuclear physics, is occurring at two successive scale levels.
The first one concerns the assemblies of quarks and gluons, whether unconfined in a plasma or bound in the nucleon and in other hadrons. The second one concerns the assemblies of nucleons which constitute the nuclei of the different atoms. The DPhN primary goal is to deepen our understanding of those systems and of the reactions enabling their studies.
Fundamental questions are linked to this goal as for instance:
SPhN activities are gathered around four research axis and one support activity in security and radiation protection:
The balance between the various research themes and applications, which mutually enrich and complement one another, is an important source of dynamism for the division.
