With the help of mathematical modeling methods we studied the evolution of whirl structures moving in a gas behind a shock wave front. This shock wave is defined by the Hugoniot relations. The Hugoniot relations allow finding the parameters of the ga

We discuss the feasibility of developing a high-power thermonuclear neutron source driven by laser pulses. Using one-dimensional numerical simulations for targets made in the form of double-sided cones, for an absorbed Nd-laser energy of ∼ 1 MJ (at

In specially designed compressed thermonuclear targets, spontaneous magnetic fields (SMF) ≥ 100 MG can be generated. We propose a conceptual design of the laser target for creating a magnetized hot (∼10–100 million K) thermonuclear plasma to mo
