Ion beam techniques using accelerators are employed for ion beam analysis (IBA) or as a tool for rapid and efficient modification of materials or for creating radiation damage in solids. Confidence in analytical techniques such as IBA, especially those based on knowledge of fundamental interaction parameters, relies on understanding the physical processes underlying the technique, and on well-defined analytical protocols. Here, we propose research on the physical processes of importance for X-ray spectroscopy (XES) methods.

The project aims to investigate the influence of structural and chemical effects on high-resolution X-ray spectra after excitation by ion beams, including the investigation of effects on K X-rays for elements from Mg to Fe, emission of satellite X-rays characteristic of multiple ionizations by heavier ions, and effects on L and M X-ray lines of heavier elements.

Also, the project will fund a significant improvement of IBA capabilities on RBIs ion microprobe by building an advanced WDXRS spectrometer and demonstrate its applicability and the importance of certain fundamental parameters in the study of cultural heritage objects and in materials research, including in-situ studies of structural and chemical changes in materials due to ion beam irradiation.

At the end of the project, the newly developed spectrometer would be available to researchers for the study of various phenomena and for interdisciplinary applications. Also, our younger researchers will gain significant experience and knowledge that will be very relevant for the development of their future careers. In addition to scientific papers, concrete results of research on cultural heritage objects are expected.
