At the General Assembly of SB RAS Director of Boreskov Institute of Catalysis Academician Valerii I. Bukhtiyarov told about the first stations of the new center of collective use “SKIF” established within the project “Akademgorodok 2.0” as well as what kind of research is expected to be conducted there.

“SKIF” in Novosibirsk is designed as a part of the Russian network infrastructure of synchrotron research of the next generation, which also includes the head object on the basis of National Research Center “Kurchatov Institute” in Protvino, Moscow oblast, as well as the specialized object in Vladivostok, Russky Island. “SKIF” belongs to the fourth generation of the equipment with the energy of 3 gigaelectronvolt and emittance of 186-60, which would allow conducting research on live objects. “These studies should improve the standing of the Siberian Branch in fundamental and applied research”, says Valerii Bukhtiyarov.

A total of 32 stations are planned to be built, the first six of them are: station of scanning microanalysis “Microfocus”, of structural diagnostics, of high-speed process studies, of XAFS-spectroscopy, of diagnostics in high-energy X-ray range, of electronic structure.

“Microfocus” station combines the ultralow emittance and the advances of X-ray optics. This station is engaged in solving several blocks of problems. First block supposes studying the structure of biopolymers including the system of human repair, transfer of hereditary information, causes and mechanisms of diseases for making pharmaceuticals. The second block of problems involves creating new materials, i.e. studying the structure and other parameters in multicomponent compounds, watching the behavior of the new materials in various conditions of pressure, temperature and radiations of different spectra. Finally, “Microfocus” station should allow studying the geomaterials, i.e. revealing the components of ore minerals, conducting the experiments at high pressure and temperatures in order to understand the geological processes and select the best conditions for synthesis of artificial minerals.

Station of structural diagnostics is planned to study the objects with the methods of X-ray diffraction. It should find application in the field of catalysts for oil processing and ecological applications as well as for the materials of various purposes, for example, thin films, systems with partially disordered hierarchy, nanomaterials, monocrystals, pharmaceuticals, etc.

Station of high-speed process studies is aimed to investigate the crystal structure of a compound in the extreme conditions of high temperatures (10000°C) and pressures (10 mln atm) formed upon the impact of shock and blast waves, powerful laser radiation, plasma, etc. It includes three sections: dynamic processes, plasma, and extremely high temperatures.

Station of XAFS-spectroscopy (X-ray absorption fine structure) and magnetic dichroism should be used for studying the electron and local structure of compounds. For example, it can help to see the centers of bonding metals in proteins or the processes of precipitation and growth of semiconducting films.

Station of diagnostics in high-energy X-ray range provides the contrast images with high resolution and in situ in hard X-ray range. For example, it could help to study the paleontological findings, new composite materials and geological samples as well as to make their 3D images.

Station of electronic structure allows studying the electronic structure in different situations: on the surface, in the volume and on the borders of phase interfaces in various materials, films and multilayer coatings of solid bodies.

Valerii I. Bukhtiyarov noted that now the stations of the second stage are being discussed: the plans include studying the structure and form of viruses with X-ray diffraction, examining the electronic constitution, structure and composition of compounds of various nature as well as the transformation of compounds with electron-beam and laser welding and with impact of the particle streams over surface. In addition to that, the works are planned to study what happens on the first wall when irradiated by the plasma streams as well as the research of the electronic and spin structure of crystals.
