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 o...

This study was carried out to describe the chemical characteristics of individual residual particles in hexagonal snow crystals, which can provide a clue to the aerosol removal mechanism during snowfall. In the present study, to collect snow crystal individually and to identify the elemental composition of individual residues retained in a hexagonal crystal, an orchestration of the replication ...

Interest and debate continues today in the U.S. and Europe over whether organic foods are healthier for the consumer. Several studies show that fruits and vegetables may contain higher concentrations of vital nutrients. Using the PIXE technique, which is a quick and inexpensive way to analyze samples, this study is inconclusive on whether eating organic is necessarily healthier for an individua...

Abstract In this work, we demonstrate the feasibility of quantitative laser-based x-ray fluorescence (XRF) combined with particle-induced emission (PIXE) (called XPIF for and fluorescence) spectroscopy analysis elemental composition in solid samples. A multi-hundred TW laser system accelerated protons produced x-rays that were impinging on samples, inducing characteristic line emissions element...

Proton-Induced X-ray Emission analysis (PIXE) constitutes a method for trace element analysis characterized by multielemental capability, detection limits in the low ppm-range and size resolution down towards a micrometre. In applications where the sensitivity of the Electron-Induced X-ray Emission (EIXE) analysis is not sufficient and where a spatial resolution not better than a few micrometre...

Nuclear microprobe at 2 MV Tandetron accelerator of Jozef Stefan Institute (JSI) was constructed in the year 2000 with the support of IAEA Technical Cooperation Project SLO/1/004. The measuring station is equipped with instrumentation for micro-Proton-Induced-X-ray-Emission (micro-PIXE), micro-Elastic Recoil Detection Analysis (micro-ERDA), micro-Nuclear Reaction Analysis (micro-NRA), Proton Be...
