The results of the studies of the compression of the plasma of cone-cylindrical nested arrays of mixed composition at current flow through them of up to 3 MA at the Angara-5-1 facility are presented. As a result of this interaction in the space between arrays,different plasma flow modes are implemented: pre-Alfvén (Vr < VА), super-Alfvén (Vr > VА), and a mode with the formation of the transition region—a shock wave (SW) between arrays, depending on the ratio of the plasma formation rates of arrays of nested array and on the ratio of their radii. New experimental data was obtained on the features of the SW region formation near the surface of the inner array and the nature of its change during the interaction. The obtained experimental results are compared with the results of simulating the plasma motion between the arrays using the three-dimensional radiation-magnetohydrodynamic code MARPLE3D.
