First results of dust injection in T-10 plasma
First results of T-10 injection experiments of the carbon dust particles with 2-10 mm diameter and 40-300 m/s velocity are presented. Different scenarios of the dust injection were tested. The dust particles ablation was studied. An approach for determination of a dust particle penetration length was developed. Measured penetration depths (3-7 cm) are compared with the simulation by the ablation model. The mm range of the separate dust particle diameters derived from the ablation data was close to sizes of the dust injected assuming that an acceleration of the separate particle is similar to the large carbon pellet in the pellet injector.ΠΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½ΠΎ ΠΏΠ΅ΡΡΡ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠΈ Π΅ΠΊΡΠΏΠ΅ΡΠΈΠΌΠ΅Π½ΡΡΠ² ΠΏΠΎ ΡΠ½ΠΆΠ΅ΠΊΡΡΡ Π²ΡΠ³Π»Π΅ΡΠ΅Π²ΠΈΡ

Comissioning of the linear accelerator-injector at the TNK facility
The industrial storage facility has been developed and manufactured at the Budker INP SB RAS. It contains an
80 MeV electron linear accelerator-injector and two electron storage rings: the lesser 450 MeV booster ring and the
main 2.5 GeV storage ring. In 2002, the work on the accelerator assembling was begun. On December, 25 this year
the accelerator was started up, and the current at the linear accelerator output was obtained. The linear accelerator
schematic together with a description of the 6 meter long accelerating DAW structure which operates at 2.8 GHz,
are presented in the paper. The first results of the accelerator start-up are as follows: the accelerated electron current
of ~50 mA with the energy of ~55...60 MeV.Π’Π΅Ρ

Geochemistry of hydrocarbons of the Terek-Caspian trough
Within the Terek-Caspian oil and gas bearing basin of the Eastern Ciscaucasia, oil deposits occur in a wide stratigraphic range of rocks of the Mesozoic-Cenozoic section, from the Jurassic, at depths from 5800 to 200 m. In the sedimentary section, carbonate and terrigenous Middle Jurassic, Lower Cretaceous, Oligocene-Lower Miocene and Miocene oil-mother rocks are distinguished. Organic matter from them have different geochemical characteristics and different maturity to realize the generation potential. The article presents the results of a comprehensive study of potential petroleum-bearing rocks and hydrocarbon fluids from the Terek-Sunzha folded zone of the Terek-Caspian Trough, including lithological, chemical-bituminological, pyrolytic, chromatographic and chromatographic-mass spectrometry investigations. A detailed description of hydrocarbon fluids at the molecular level and genetic correlations of oil-oil and oil-organic matter are given. Specific features of the oil deposits of the Mesozoic-Cenozoic section are noted. Among the studied bitumens, the chromatographic characteristics of the extractable organic matter from the Khadum carbonate-clayey deposits and oils from the Cretaceous and Neogene reservoirs are most similar. The composition of a complex natural mixture of hydrocarbons from various sources, with different maturation during the geological history of the region, does not allow making unambiguous conclusions about the source or sources of hydrocarbons for the deposits of the Terek-Caspian Trough

Nature of phase transitions in ammonium oxofluorovanadates, a vibrational spectroscopy study of (NH4)3VO2F4 and (NH4)3VOF5
Two ammonium oxofluorovanadates, (NH4)3VO2F4 and (NH4)3VOF5, have been in-vestigated by temperature-dependent infrared and Raman spectroscopy methods to determine the nature of phase transitions (PT) in these compounds. Dynamics of quasioctahedral groups was simulated within the framework of semi-empirical approach, which justified the cis-conformation of VO2F43β (C2v) and the C4v geometry of VOF53β. The observed infrared and Raman spectra of both compounds at room temperature (RT) revealed the presence at least of two crystallographically independent octahedral groups. The first order PT at elevated temperatures is connected with a complete dynamic disordering of these groups with only single octahedral state. At lower temperatures, the octahedra are ordered and several octahedral states appear. This PT is the most pronounced in the case of (NH4)3VOF5, when at least seven independent VOF53β octahedra are present in the structure below 50 K, in accordance with the Raman spec-tra. Ammonium groups do not take part in PTs at higher and room temperatures but their reorientational motion freezes at lower temperatures
