The aim of this paper is to analyze the various uses of Stark broadening data for non-hydrogenic lines emitted from plasma, obtained with the modified semiempirical method formulated 40 years ago (1980), which are continuously implemented in the STARK-B database. In such a way one can identify research fields where they are applied and better see the needs of users in order to better plan future work. This is done by analysis of citations of the modified semiempirical method and the corresponding data in international scientific journals, excluding cases when they are used for comparison with other experimental or theoretical Stark broadening data or for development of the theory of Stark broadening. On the basis of our analysis, one can conclude that the principal applications of such data are in astronomy (white dwarfs, A and B stars, and opacity), investigations of laser produced plasmas, laser design and optimization and their applications in industry and technology (ablation, laser melting, deposition, plasma during electrolytic oxidation, laser micro sintering), as well as for the determination of radiative properties of various plasmas, plasma diagnostics, and investigations of regularities and systematic trends of Stark broadening parameters.

“…The basic laws of motion of the plasma stream outside the MPC channel were studied in previous experiments. The comparison of experimentally measured parameters of a plasma stream and theoretical estimates of their values was done for identical experimental conditions [9,12,15]. It is known [1,15] that the density and the temperature of a compressed plasma stream strongly depend on the initial conditions at the entrance of the accelerating channel.…”

Multiplexing Creation of a Compression Zone in the Plasma Steam MPC under Different Initial Conditions

et al. 2017

View full text Add to dashboard Cite

The analysis of fundamental properties of the compression zone in the self-compressed plasma streams generated by a magnetoplasma compressor (MPC) is carried out. The main attention is attended to the research of the dependences of basic plasma parameters in a compressed plasma stream depending on the initial conditions. It has been shown experimentally that the reduction of the initial concentration of a working gas leads to an increase of the plasma density in the compression zone. The detailed studies of the spatial distributions of currents in the plasma flows are fulfilled for different initial concentrations of a substance in the accelerating channel of MPC. Under the experiment conditions, it is found that a decrease of the initial concentration of a working gas leads to the displacement of the currents from the compression zone. K e y w o r d s: plasma dynamics, magnetoplasma compressor, compression zone.

The formation of the current-sheet-like structure under the influence of the external magnetic field in pinching plasma flows generated by the magnetoplasma compressor has been studied. A set of magnetic and electric probes were used to measure the self-generated magnetic field, electron temperature, and electric field locally with sufficiently high temporal and spatial resolution. The data obtained from the probe measurements were used to plot the spatial distributions of electric current and drift velocity in the plasma stream to identify the patterns of plasma flow. In the presence of external magnetic field, the current density, electron temperature, and the ion saturation current reach a peak in close proximity to the sheet. Measurements indicate the outflow of two electron jets of different temperatures from the layer.
