Swift heavy ions (SHI) penetrating through a solid lose main part of the energy to the electronic stopping. The extremely high level of the electronic excitation generated by incoming ion at the femtosecond scale is followed by relaxation of the perturbed electron ensemble. Subsequently, the acceleration of target atoms occurs at sub-picosecond times, resulting in the formation of a nanometric damaged region within hundreds of picoseconds after the ion passage. These structural changes can affect its physical, chemical, and mechanical properties of the irradiated target. Due to these features, accelerated ion beams serve as a versatile tool for the patterning and modification of nanometric materials [1,2], as well as the investigation of radiation stability against cosmic rays and fission fragments.
