Description

Recently, the CENTA laboratory was established at Faculty of Mathematics, Physics and Informatics, Comenius University in Bratislava. The laboratory comprises the system for production of various ion beams from solid and gaseous samples, the energy and mass separation and the 3 MV tandem accelerator, that is used for acceleration of the ions up to tens of MeV. The beams can be used for several IBA (ion beam analysis) techniques, like PIXE (particle induced X-ray emission), PIGE (particle induced gamma-ray emission), RBS (Rutherford back-scattering). In this work, the PIGE was used to study concentrations of several elements like Al, Na and F in atmospheric aerosols. BEGe detector from Canberra Industries was used for detection of gamma-rays from inelastic scattering of accelerated protons in thin samples. The aerosols were collected in weekly intervals at the university campus and reflect the composition of aerosols in industrial and urbanized area. For the analysis, the preparation of thin samples was developed from the collected aerosols and NIES CRM No. 28 Urban Aerosol reference material was used for the calibration of the system.
