Aim of the proposed project is to study effects of the swift heavy ion irradiation on amorphous materials. Impact of this type of ion often leads to nanoscale damage called an ion track. On the material surface, ion tracks can be observed by atomic force microscopy and small angle X-ray scattering, while in the bulk these nanoscale objects can be investigated using transmission electron microscopy. Nowadays, molecular dynamics (MD) simulations are powerful computational tool that help researchers understand better processes leading to the formation of the ion track. Proposed project will be implemented both as an experimental and theoretical research. We propose to conduct three experiments and also to make three theoretical studies (using MC code Geant4 and MD code LAMMPS). From these six topics we plan to publish six research papers by the end of the project. The project also aims to build our capacities for the research. With the funds from this project, we will upgrade AFM set-up we are already using intensively, and also, we plan to upgrade HPC cluster that will enable our MD simulations of ion track formation. The later will firmly establish this line of theoretical research at our Institute, that previously had to be outsourced. Finally, in the third year of the project we also propose to organize the leading conference in this field of research, i.e. the International conference on ''Swift Heavy Ions in Matter'' in Croatia.To achieve the proposed research objectives, our team of experienced researchers from RBI will be complemented with colleagues from abroad, and also with postdoctoral researcher we plan to hire for two years. Hiring of the PhD student is also anticipated at a later time.
