Non-self-sustained arc discharge in vapors of constructional materials of nuclear power engineering

Autor: Borisenko, A.G., Kostin, E.G., Rokytskyi, O.А., Fedorovich, O.A.

The paper presents the results of experimental studies of the conditions of ignition and burning for non-selfsustained arc discharges in nickel and tantalum vapors. The investigations were carried out with the aim of developing new methods for effici

Dependence of nonequilibrium of radiation of a pulsed discharge in water in the visible range on the electric field strength

Autor: Fedorovich, O.A.

The results of experimental studies of nonequilibrium of radiation in the visible range of a nonideal plasma (NP) are presented. The plasma was produced in pulsed discharges in water (PDW) with minimum amount of impurities. The PDW was initiated by e

On features of the radiation from pulsed discharges initiated by thick wires in water

Autor: Fedorovich, O.A., Voitenko, L.M.

The investigation results on the distribution of the plasma channel radiance intensity in the visible spectral region are reported. The pulsed discharge in water is initiated by the Tungsten wire (Ø 300 μm) explosion under initial battery voltage o

About influence of energy of electrons and ions on speed of electron- and ion-stimulated plasmachemical etching of silicon

Autor: Fedorovich, O.A., Kruglenko, M.P., Polozov, B.P.

The experimental dependence of the etching rate monosilicon of self-bias voltages on the active electrode at other constant conditions in the discharge is shows. With increasing negative bias potential monosilicon etching rate increases, then reaches

About unrealization of tungsten lines up to the ground state in the nonideal plasma of pulse discharges in water

Autor: Fedorovich, O.A.

The paper considers the dynamics of tungsten impurity absorption line appearance in the plasma channel of the pulse discharge in water (PDW) during the plasma relaxation process. In the initial stage of discharge (3 µs) any tungsten and hydrogen abs
