Center for collective use of appliances "High-vacuum analytical system UHV-ANALYSIS-SYSTEM" is designed to conduct research in the field of electronic structure, elemental and phase composition of the surface of solids without their destruction. This center was created on the basis of Frantsevych Institute for Problems of Materials Science of the National Academy of Sciences of Ukraine for the rational use of modern equipment by scientific institutions and organizations of the National Academy of Sciences of Ukraine. The main task of the Center " High-vacuum analytical system UHV-ANALYSIS-SYSTEM" is to provide scientists of the NAS of Ukraine the opportunity to conduct research on modern devices, which are serviced by qualified personnel capable of maintaining equipment in high quality working conditions and provide consulting services. Techniques used in the center: 1) X-ray photoelectron spectroscopy; 2) ultraviolet spectroscopy, Auger spectroscopy; 3) diffraction of slow electrons. Elements analyzed: all except hydrogen.
