Ladygina M. Spectral characteristics of compression plasma in magnetoplasma compressor and plasma focus systems

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. The formation of dense near-surface plasma layers is studied at the interaction of powerful plasma compression streams with materials surfaces. 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. 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. The optimal initial conditions were determined to achieve maximum plasma parameters using spectroscopic measurements.
