MAGNETIC PARTICLES` FORMATION IN CONDITIONS OF THE LOW-TEMPERATURE PLASMA AND MAGNETIC FIELD
01.00.00 Physical-mathematical sciences
Description
Chemical processes are often connected with use or formation of condensed dispersed phase (CDP). Dispersed particles can change mobility of charges, as well as other parameters of the low-temperature plasma. The aim of this work is to study the effect of magnetic field on the processes of dispersed particles formation in argon-oxygen plasma containing iron and carbon atoms at atmospheric pressure. The equilibrium composition of iron and carbon atoms containing mixture simulated at temperatures of 1000-5000K for optimization of the plasma-forming gas composition. It is shown that in case of oxygen excess, the CDP particles contain only iron oxides. The literature data about the phase transition processes in a low-temperature plasma, as well as the data about the processes with participation of ferromagnetic particles in a constant magnetic field analyzed. The results of investigations of the dispersed particles forming in argon-oxygen plasma of arc discharge in the presence and in the absence of the magnetic field are shown. The formed disperse phase was deposited on the substrates and studied by the electron microscopy and X-ray methods. It was found that with the lack of oxygen the size of the iron-oxide particles created in the arc discharge containing iron and carbon is affected by magnetic field: in a magnetic field of 10 mT the particles are larger than in its absence

INTERFEROMETRIC METHOD OF LASER RADIATION TRANSMISSION USING FREE SPACE OPTICS
01.00.00 Physical-mathematical sciences
Description
The analysis of the various conditions of the two (four) laser radiation streams coherent addition was realized. It is shown that it is possible to create devices providing continuous subtraction of waves. In such radiation stream a continuous subtraction on the line can be replaced by the continuous addition on the photomultiplier by using a dispersive delay line. The research results can be used for creation of modern open atmospheric connection lines

DEVELOPMENT OF A METHOD FOR DIVIDING CARBON ISOTOPES WITH MAGNETIC AND NON-MAGNETIC NUCLEI
01.00.00 Physical-mathematical sciences
Description
The dynamics of the state of spin of the radical oxygen-carbon pair are observed. By way of mathematical modeling, optimal conditions for conducting experiments to obtain the maximum meaningful coefficient of division of carbon isotopes was established
