A converging shock wave for ignition of a pre-compressed target of laser thermonuclear fusion
Abstract:
The formation of a convergent shock wave in a homogeneous spherical target is studied, the outer layer of which is heated by a stream of monoenergetic fast electrons with a given particle energy. The ablation pressure generating the wave is formed by the spherical expansion of a layer of a heated substance, the optical thickness of which remains constant throughout the heating process and is equal to the product of the initial depth of heating by the thickness of the layer. The investigations were performed on the basis of numerical calculations on a one-dimensional hydrodynamic program with reference to one of the most perspective methods of ignition of a target of laser thermonuclear fusion - the ignition of a pre-compressed target by a shock wave.
