“…It allows obtaining beams of high current density due to a focusing system. There is also a possibility of obtaining beams of uniform current distribution at a target plane and of preserving size of a focused beam at energy variation without a sample shift [4]. Tandem accelerators that are a basis for nuclear microprobe setup allow obtaining ion beams in a wide range (from hydrogen to bismuth).…”

The application of scanning nuclear microprobe for study a radiation-induced migration of impurities at the grain boundaries in structural materials was considered. The work describes the sample preparation for a further irradiation of microscopic areas which include a few grains. Copper samples with deposited sulfur film were used in the present work. Determinations of a chemical composition of the samples, as well as a mapping of the element distribution, were based on the analysis of characteristic paticle induced X-ray emission (PIXE). Two-dimensional distribution maps of elements, that revealed a presence of randomly distributed inclusions of silicon as a result of mechanical treatment, were obtained using the method of micro-PIXE. The quality difference of sulfur films deposited by thermal evaporation and a drop method was shown.
