Ladygina M.S. Spectral characteristics of compression plasma streams in magneto-plasma compressor and plasma focus systems. ‒ Research Project, Manuscript copyright. Thesis for the scientific degree of the candidate of physical and mathematical sciences by specialty 01.04.08 – Plasma physics. – National Science Center «Kharkiv Institute of Physics and Technology» Institute of Plasma Physics. – V. N. Karazin Kharkiv National University, Kharkiv, 2018. The thesis contains the experimental results of the initial and boundary conditions influence on the peculiarities of the compression plasma flows dynamics and the compression region formation in pinch discharges of magnetoplasma compressor (MPC) with the use of working gases of various masses and their mixtures. In addition, the formation of dense near-surface plasma layers is studied at the interaction of powerful plasma compression streams with materials surfaces. In particular, the spectroscopic methods of the compression plasma parameters of different ions sort analysis in plasma focus and MPC have been developed, dynamics of dense magnetized plasma has been investigated using different working gases (nitrogen, helium, xenon, argon, deuterium) and mixtures of gases with different atomic masses are investigated. For the first time, an analysis of the similarity conditions of the discharge development and the features of the plasma compression was carried out with various sorts of ions using. Thus, the optimal initial conditions, gas injection features and other discharge characteristics were determined to achieve maximum plasma parameters and intensity of electromagnetic radiation in the selected range of wavelengths and energies using spectroscopic measurements.
