Ion beam analysis in material research
Bočan, Jiří ; Macková, Anna ; Malinský, Petr
In 2005, a new accelerator Tandetron 4130 MC produced by HVEE, The Netherlands, unique in the Czech Republic, was installed in the Laboratory of Nuclear Analytical Methods at the Nuclear Physics Institute. During the whole year 2006, construction and development of two beamlines and four experimental setups for the nuclear analytical methods proceeded. These methods namely are RBS (Rutherford Back-Scattering), TOF-ERDA (Elastic recoil detection analysis with time-of-flight measurement), ion implantation and RBS-channeling. The first three methods are presented in detail in this article.

Ion beam analysis in material science
Macková, Anna ; Bočan, Jiří ; Malinský, Petr
In this paper we presented our results of complementary research using ion beam analysis for study of materials. Combination of RBS, PIXE and ERDA method enables us to characterize the elemental composition and the elemental depth profiles of complex multi-layer systems or study complicated difussion processes in different applications of material sciences. We described the newly installed methods TOF-ERDA and RBS-channeling and their application on material characterization and the results of testing of these methods at our workplace.

What is hidden in nuclei, let it show on the table...
Macková, Anna
The main goal of this contribution was to show using the simple way several experiments which demonstrated the important features of nuclear radiation (absorption, penetration abilities, scattering of particles). People are confronted with radiation every day (cosmic radiation, natural radioactivity). We presented wide range of applications of nuclear physics in our life (radiology diagnostics of tumours, ion beams for material research, fusion reactors for future source of energy).

What is the function and the application of TANDETRON accelerator?
Macková, Anna
The main task of contribution was to introduce new unique equipment which was attracted by journalists also. New accelerator TANDETRON enables wide range of applications of ion beams in new technologies. The laboratory of TANDETRON joined several parts of material research. The interdisciplinary research is nowadays the most growing and progressive discipline. The main goal of this publication was to show the application of ion beams and accelerators. This should contribute to the change of laic negative point of view on this discipline.

Trip into the atomic nuclei and back
Macková, Anna
Several examples of applications of the nuclear physics are presented in this article. Nuclear and subnuclear physics enables us to describe the fundamental level of existence of matter and to contribute to the research and development of new materials and technologies simultaneously. Radioizotopes nowadays are very helpful in diagnostics and therapy of cancer. The main task of this article was introducing of nuclear physics as a broad research discipline with fundamental results and also functional applications.

New possibilities of nuclear analytical methods using accelerator Tandetron 4130 in Nuclear Physics Institute of ASCR
Macková, Anna
The new accelerator (unique in Czech Republic) makes realisable to fundamentally develop the present analytical possibility and to put on the new technique of material modification and synthesising of advanced materials and structures. We report on new analytical methods - RBS-channeling, ERDA-TOF, ion microprobe. These methods give us opportunity to study crystalline materials in interstitial positions, to achieve the lateral resolution less than 1 micrometer and the depth resolution better than 1 nm. New accelerator produces wide range of ion masses, so the ion implantation is very important material modification technique.
