Formation of nanostructures using swift heavy ions

Interaction between “swift heavy ion” (m>20 u, E>1 MeV/u) and target material is a violent one: almost all kinetic energy of the incoming particle is deposited in a small cylindrical volume around its trajectory. Extremely high density of deposited energy can lead to various kinds of material modifications, for example amorphization of crystalline lattice. This permanent damage caused by swift heavy ion is called ion track. Traditionally, investigations of swift heavy ion tracks were conducted at large accelerator facilities (GANIL, GSI), while smaller ones were focused on ion beam analysis activities. Recently, it was shown that restriction to formal definition of swift heavy ion is unnecessary since even lighter and less energetic ions can induce significant changes in a wide range of materials [1]. Thus, new possibilities have opened up for utilization of small and medium size accelerator systems in the field of material modifications
