“…For this, the values of ṁin / ṁout were estimated using equation (2) for the ratios of the radii of the arrays r in /r out = 0.3, 0.5, 0.6, 0.7, 0.8, and 0.9, which were used in our experiments. The ratio of the coefficients K in /K out included in equation ( 2) was taken from the experimental data for various substances of wires or fibers, which are most fully presented in the works [52,55], and the ratio of currents I in /I out was measured using miniature magnetic probes located between the arrays in the immediate vicinity from the surface of the inner array [31,45]. The results of the comparison of the MHDpredictions on the nature of the plasma flow between arrays of nested array of mixed composition with experimental data are presented in this work [44].…”

The results of experiments on the study of plasma compression of nested wire arrays of mixed composition and the generation of powerful pulses of soft X-ray radiation (SXR), carried out on a powerful electrophysical facility Angara-5-1 at a current level of up to 3 MA, are presented. Based on the latest experimental data on the intensity of plasma formation of various substances m& (in μg/(cm2×ns)) [1] and on the features of the dynamics of plasma compression in nested arrays [2], a nested wire array design has been developed which makes it possible to obtain a high peak SXR power in comparison with the known designs of single and nested tungsten wire arrays. During the implosion of nested arrays of mixed composition, consisting of plastic fibers and tungsten wires, shorter and more powerful SXR pulses were obtained with a maximum peak power PSXRmax~10 TW with a FWHM duration of ~5 ns compared to the parameters of SXR pulses upon compression of single tungsten arrays: PSXRmax~5 TW and FWHM~10 ns. Thus, under the conditions of our experiments, we have shown the possibility of a twofold increase in the peak SXR power during compression of nested arrays by optimizing their design.

Extreme states arise when a substance is exposed to powerful shock, detonation and electric explosive waves, concentrated laser radiation, electron and ion beams, during powerful chemical and nuclear explosions, hypersonic motion of bodies in dense planetary atmospheres, high-speed impact, and in many other situations characterized by extremely high pressures and temperatures. The study of matter under extreme conditions is one of the most urgent and intensively developing fundamental scientific disciplines, located at the intersection of plasma physics, nonlinear optics, condensed state, nuclear, atomic and molecular physics, and relativistic and magnetic hydrodynamics. In our country, research in the field of physics of high energy density and extreme states of matter is dynamically developing thanks to the active cooperation of the Russian Academy of Sciences and the Rosatom State Atomic Energy Corporation.
