dc.description.abstract© EPS 2019. All rights reserved.The results of plasma compression studies of nested wire and fiber arrays with current flowing through them are presented in this work. Experiments were made on the Angara-5-1 facility with current up to 4 MA. Current implosion of nested arrays represents a unique opportunity to simulate the interaction of a plasma flow with a magnetic field. Different plasma flow regimes in the space between the inner and outer arrays were obtained: sub-Alfven (Vr<V?), super-Alfven (Vr>V?) and a mode with the formation of a transition region-shock wave (SW)-between the arrays, depending on the radii ratio of the inner and outer arrays. The dependence of these flow regimes on the plasma production rate of the inner and outer arrays is shown. At certain parameters of nested arrays, a quasi-closed shell is formed in the azimuthal direction around the inner array. At the same time, the plasma of the outer array surrounds the inner and stabilizes its compression. The suppression of MRT instabilities during plasma compression of the inner array leads to the formation of a stable, compact Z-pinch and the generation of a short-time soft X-ray pulse.
