Opis:
The analysis of a plasma impurity composition in many plasma systems (such as coaxial plasma accelerators, magnetic- plasma compressors, plasma-focus devices, and others) is of great importance for plasma physics. In this work we have proposed a new spectral method for the determination of impurity concentrations in relation to the concentration of the main plasma (made of hydrogen in our case). This technique can be used e.g. for diagnostics of a peripheral zone in Plasma-Focus (PF) discharges, where LTE conditions must be fulfilled. Advantages of this method in comparison with other methods, as well as possible errors, are considered and discussed.

Opis:
Comparative studies of the parameters both pure helium and helium-xenon plasma have been fulfilled in a magneto-plasma compressor (MPC). The current-voltage characteristics of MPC accelerating channel and the maximum plasma velocity of (6-8) x 106 cm/s changed negligibly under local xenon injection to compression zone. Nevertheless, the xenon addition causes a growth of maximal plasma pressure up to of 2.3 MPa, an increase of plasma radiation from the compression zone. The plasma density achieved 1018 cm.

Opis:
A pulsed coaxial plasma accelerator was utilized in the experiments discussed in this paper. Plasma streams with ion energy up to 2 keV, plasma density 2-3×1014 cm-3, and plasma energy density 5-40 J/cm-2, were generated. Such a plasma was used for the surface modification of different constructional steels. Experimental results on improvement of physical properties of metal surfaces (first of all tribological characteristics), under their irradiation by pulsed plasma streams are presented. Optimization of the treatment process was carried out varying plasma energy flux, plasma density, and energy of ions. It was shown that microhardness of the steel samples, both non-quenched and previously quenched, was increased by several times after plasma irradiation. The main attention was paid to the analysis of wear resistance of the treated material by using different methods of wear tests. The possibility to achieve a sufficient decrease of the wear rate of the treated samples was demonstrated.
