The object of research - plasmooptical systems, in particular plasma lenses of a space charge, a plasmooptical magnetron of direct and reverse action. The purpose of the work - theoretical research using physical and mathematical modeling of the properties of low-temperature plasma in plasmooptical systems and the search for ways of constructing plasmooptical systems with new capabilities and improved characteristics for use in promising fields of science and technology, in particular, for the creation of protective coatings in various areas of industry, science and technology. Research methods include: - methods of theoretical and mathematical physics, namely hydrodynamics and physical kinetics, to create the corresponding systems models; - methods of numerical modeling, including the development of adequate and effective numerical algorithms for the implementation of the created physical models; - methods of computer calculations, including calculations by particle methods, hybrid models, Monte Carlo methods for the processes of particle motion in a plasma medium; methods for determining the compliance of calculated and experimental data; The report consists of introduction, 9 chapters of the main part, conclusion and list of links. Based on the obtained experimental data, the report proposes a model of plasma dynamics of magnetron-type gas discharges. The model is based on the assumption that there are three quasi-autonomous regions in the diode discharge gap that differ significantly in the nature of current transfer. A hydrodynamic analysis of the plasma-dynamic processes of a cylindrical gas discharge in a transverse magnetic field with a closed electron drift is made and a model of stationary discharge characteristics depending on the system parameters is created. Simpler analytical solutions are found and analyzed. It was found that there exists an optimal magnetic field that can contain highly energetic electrons at the cathode. There they ionize the neutrals, enhance ionization and increase the number of ions, which, in turn, accelerate, move to the cathode and are able to acquire high energy. A computer simulation of a plasma-optical magnetron in a cylindrical coordinate system in a hydrodynamic description is carried out. The formation of a virtual anode is modeled, and the optimal mode of operation is found. Product Description popup.authors Бєлошенко Микита Анатолійович Білодуб Анатолій Макарович Борисенко Анатолій.
