The effects of the electronic energy loss of fast ions in materials have gained increasing
importance for modern science and technology over the past years. The research field
includes, among others, permanent materials modification of solids by heavy ions. New,
unexpected findings like the self organisation of the irradiated material have been
observed. Besides the fundamental research concerning the interaction of ions with
matter, ion beams are exploited in applied research, e.g. the study of radiation hardness
of electronic compounds for aerospace. The high quality of ion beams from a cyclotron
allows challenging novel applications and the elaboration of existing techniques: Hightech
miniature filter production by heavy ion irradiation as well as eye tumour therapy
profit from the high beamy stability, whereas materials analysis benefits from the low
beam emittance. Different applications, ranging from high current irradiations to
single ion track applications, will be presented. Examples from materials analysis
using heavy ions for ERDA (Elastic Recoil Detection Analysis) of complex layered
structures like solar cells as well as the non-destructive analysis of art objects, e.g.
Egyptian coffin masks, by high energy PIXE (Proton Induced X-ray Emission) will be
shown. The specific requirements for the accelerators will be discussed.
