The paper consists of introduction, five chapters, general conclusions, bibliography containing a list of 122 sources, 123 pages (until the bibliography), 166 formulas, 53 figures, and 4 tables. The obtained results are published or/and presented in 44 scientific papers in specialty journals or volumes of scientific exhibitions presented oral or by poster.
Field of study – physics.
The purpose of dissertation was interpretationd and presentation of obtained results of theoretico-experimental investigations aimed at the physical processes of excitement and relaxation of gaseous media in view of plasma formation and, respectively, analisys of its interaction with the substance.
The objectives of dissertation are: i) presentation of actual state on the investigations of physical processes of excitement and relaxation of particles contained in the gaseous media; ii) presentation of theoretical and experimental considerations on the conditions of plasma formation in the laboratory conditions; iii) design and development of experimental setup for plasma formation in the laboratory conditions; iv) presentation of mathematical model on the investigations of physical processes in the gaseous media and plasma interaction with the substance; v) presentation of experimental results obtained at the study of interaction of plasma produced by developed in the thesis device with solid substance.
Original elements obtained and presented in the dissertation: i) design and development of electrodes of special construction used for pulsed electrical discharge plasma formation without additional devices for preventive ionization of the studied gaseous medium; ii) the use of the plasma in multiphotonic excitement of optical glass molecules and the appearance of secondary radiation in it; iii) micro- and nano-structures formation by interaction of plasma obtained by the use of developed in the thesis device with metal surfaces.
The important scientific problem: scientific explixation of physical processes of excitement and relaxation of gaseous media molecules with the aim of plasma formation and its interaction with substance (color optical glass and metal surfaces).
