Research activities description

The Materials and IRradiation (MIR) research topic of IJCLab is focusing on materials for energy applications (mostly nuclear energy), with a special emphasis put on the role played by ion beams, either to modify materials properties or to generate extreme irradiation conditions, for fundamental studies related to Solid State Chemistry and Physics.

A pertinent application of ion beams is the simulation of radiation effects in materials that could be placed in severe radiative environments. This topic concerns the qualification of the nuclear fuel, the matrices used for the confinement and/or transmutation of nuclear waste (fission products, actinides), and the evaluation of structural and fuel cladding materials for nuclear reactors of the next generations (Gen IV and fusion). Such experiments are based on the possibility to use ions of various masses at energies ranging from a few tens of keV up to a few hundreds of MeV, covering thus a broad stopping power range. They allow for example the simulation of radiation effects due to the uranium fission by using swift heavy ions, or the disintegration of actinides by using low energy heavy ions and MeV alpha particles, or the simulation of light gas injection in fission and fusion energy reactors. Low energy ion beams are also used for ion beam synthesis of materials: ions are incorporated into a solid matrix and a subsequent thermal annealing usually favors the out-of-equilibrium formation of nano-precipitates following the typical ion beam synthesis scheme.

For all these studies, the investigation of the fundamental mechanisms of ion-solid interactions applied to materials science is central, and it represents a vast research field in which some basic questions remain to be elucidated, in particular by coupling advanced experiments and modelling.
