Plasma decay in high-voltage nanosecond discharges in oxygen-containing mixtures
Plasma Physics Reports - Tập 42 - Trang 59-67 - 2016
E. M. Anokhin, M. A. Popov, I. V. Kochetov, N. L. Aleksandrov, A. Yu. Starikovskii
Plasma decay in high-voltage nanosecond discharges in CO2: O2 and Ar: O2 mixtures at room gas temperature and a pressure of 10 Torr is studied experimentally and theoretically. The time dependence of the electron density during plasma decay is measured using microwave interferometry. The time evolution of the charged particle density, ion composition, and electron temperature is simulated numerica...... hiện toàn bộ
Determination of energy release zones arising due to current losses in the convolution region of the magnetically insulated transmission lines of the ANGARA-5-1 facility
Plasma Physics Reports - Tập 41 - Trang 441-443 - 2015
E. V. Grabovski, A. N. Gribov, Ya. N. Laukhin, A. O. Shishlov
Among the factors limiting electromagnetic pulse transmission to the load in high-power electro-physical facilities, current losses in magnetically insulated transmission lines (MITLs) are of significant importance. One of such facilities is ANGARA-5-1—a multimodule facility with an output electric power of up to 6 TW. A fairly complicated configuration of the magnetic field in the convolution reg...... hiện toàn bộ
Experimental Dependence of the Neutron Yield on the Discharge Current for Plasma Focus Chambers Filled with Deuterium and Deuterium–Tritium
Plasma Physics Reports - Tập 45 - Trang 334-344 - 2019
Yu. V. Mikhailov, B. D. Lemeshko, I. A. Prokuratov
Results of measurement of the mean neutron yield from plasma focus (PF) chambers filled with deuterium and deuterium–tritium are compared for various Mather-type and spherical PF devices at discharge currents in the range of 200−1000 kA. On the basis of the experimental results, an expression for the ratio of the neutron yields ...... hiện toàn bộ

RF discharge in CO2 laser mixtures at moderate pressures
Plasma Physics Reports - Tập 28 - Trang 63-70 - 2002
S. A. Starostin, K. J. Boller, P. J. M. Peters, Yu. B. Udalov, I. V. Kochetov, A. P. Napartovich
The voltage-power characteristics and spatial structure of an RF discharge in the mixtures of CO2 and N2 molecular gases with He at total pressures of tens of torr are studied. One-dimensional numerical simulations of an RF discharge are carried out within two approaches: (i) the distribution function and the related kinetic coefficients are assumed to be functions of the local reduced field, and ...... hiện toàn bộ
Ion-acoustic solitons in Bi-Ion dusty plasma
Plasma Physics Reports - Tập 34 - Trang 955-962 - 2008
V. V. Prudskikh
The propagation of ion-acoustic solitons in a warm dusty plasma containing two ion species is investigated theoretically. Using an approach based on the Korteveg de Vries equation, it is shown that the critical value of the negative ion density that separates the domains of existence of compression and rarefaction solitons depends continuously on the dust density. A modified Korteveg de Vries equa...... hiện toàn bộ
Development of Idea of Plasma-Optical Mass Separation
Plasma Physics Reports - Tập 45 - Trang 46-56 - 2019
N. A. Strokin, V. M. Bardakov
The paper presents the history of the origination and development of A.I. Morozov’s idea of plasma-optical mass separation (POMS-E). The problems that arose in the initial stage of its practical implementation are noted. Changes in Morozov’s POMS-E scheme of the collectors of separated ions and the system for the formation of neutralized ion beams are described. Accompanying plasma effects leading...... hiện toàn bộ
Instabilities of a circularly polarized wave with trapped particles in an isotropic plasma
Plasma Physics Reports - Tập 39 - Trang 327-333 - 2013
V. L. Krasovsky
The structure and stability of a transverse electromagnetic wave propagating with a velocity lower than the speed of light in an unmagnetized plasma are considered. The stationary finite-amplitude wave is described by exact solutions to the Vlasov-Maxwell equations. However, unlike the well-known electrostatic analog, the Bernstein-Greene-Kruskal wave, the wave structure is determined to a large e...... hiện toàn bộ
Studies of runaway electrons in the Globus-M tokamak
Plasma Physics Reports - - 2004
A. Shevelev, I.N. Chugunov, В. К. Гусев, Yu. V. Petrov, V. V. Rozhdestvenskiǐ, A. B. Mineev, N. V. Sakharov, D.N. Doinikov, A. L. Izotov, S. V. Krikunov, V. O. Naidenov, K.A. Podushnikova, I. A. Polunovskii, D. Gin, A. I. Chugunov
A phenomenological model of the current filamentation instability driven by cathode processes in the Livermore spheromak
Plasma Physics Reports - Tập 29 - Trang 605-617 - 2003
D. D. Ryutov, R. H. Cohen, D. N. Hill
The current density on the open field lines of the Livermore spheromak (SSPX) typically exceeds the saturation current density of the bulk plasma. We assume that the mechanism that provides conditions for that is associated with the formation of a thin layer near the cathode surface, where both the plasma and the neutral density are higher than in the bulk plasma and where intense ionization occur...... hiện toàn bộ
