Nuclear Physics Applications / Research

Shortly after my start as staff scientist at the Institute of Nuclear Physics of NCSR “Demokritos”, I joined the applications program of the Institute. My first task was to contribute to the installation of a 4-axis channeling chamber under the guidance of Carl J. Maggiore from the Los Alamos National Lab (LANL). This apparatus, together with an existing PIXE/PIGE chamber and an older (but still operational) large scattering chamber (“Tecnolics”), were the major instruments for IBA at the Lab. In the meantime a micro-PIXE setup and an external ion beam setup have been installed. The former one was purchased (≈350 k€) with funds from a competitive project (LIBRA) that I was granted by the European Commission.

As in most of the papers published so far, the scientific problem addressed is very specific, even a brief description of the work presented therein would require a lot of pages. Overall, the majority of the papers refer to materials analyses with well-established IBA methods, like Rutherford Backscaterring Spectroscopy (RBS), Nuclear Reaction Analysis (NRA), Proton-Induced Gamma- or X-ray Emmission (PIGE/PIXE). So far the relevant publications are cited by more than 170 papers.

In addition to the aforementioned publications, I would like to refer to one specific paper entitled “Beryllium determination in dental alloys using a nuclear analytical technique”, because I really enjoyed working for this project. The results of the measurements have shown that the concentration of the toxic Be in many alloys available in the market for dental purposes exceed the limit set by health organizations!
