Studies of the optical properties of a nonequilibrium plasma in the MKV-4 facility

Results are presented from experimental and theoretical studies of a glowing plasma object emerging behind a shock front that propagates through the background gas at a pressure of p₀ = 6 torr after laser irradiation of a hollow spherical target. The results of calculations are compared to the experimental results obtained in the MKV-4 device (a component of the Iskra-5 facility).     

Feasibility of igniting thermonuclear reaction during the gas-dynamic compression of a capsule filled with a gaseous DT mixture by a compact high-speed plasma liner

Plasma Physics Reports - The feasibility is considered of igniting thermonuclear reaction during the gas-dynamic compression of a capsule filled with a gaseous DT mixture by a compact high-speed...     

Dependence of radiation from a laser-produced plasma on the plasma composition

Results are reported from calculations of how the radiation spectrum from a laser-produced plasma depends on the gold concentration in a target made of a gold-copper alloy. Calculations were carried out with the SND code by using the photon absorption coefficients obtained from the THERMOS code. The experimental data are interpreted by comparing them with the calculated results.     

Studies of the optical properties of laser plasmas produced by irradiating spherical targets

Results are presented from studies of the spectral characteristics of a glowing plasma object that forms behind a shock wave propagating in a background gas at a pressure of 1 Torr after laser irradiation of a spherical organic target in the MKV-4 device (a component of the Iskra-5 facility). The experimental data are compared to the results of calculations.     

Study of mechanisms for magnetic field diffusion into an expanding laser plasma

The interaction of plasma clouds generated during laser irradiation of a spherical target in a background gas with a magnetic field was studied on the MKV-4 test bench of the Iskra-5 facility. The dynamics of the plasma cloud expansion in a 300- to 500-Oe magnetic field was investigated using magnetic and probe diagnostics. The results obtained are compared with calculations by different models of laser plasma diffusion in a magnetic field.     

Interaction of plasma clouds produced from two laser targets

Results are presented from studies of the interaction of two plasma clouds produced from two different-type laser targets in an ambient gas in the MKV-4 stand of the Iskra-5 facility. The experimental data are compared with the results of numerical simulations.
