High-gain direct-drive laser fusion with indirect drive beam layout of Laser Mégajoule

Abstract

A new solution for high-gain direct-drive fusion with the indirect drive beam irradiation of the Laser Mégajoule is presented here. This solution uses 2 rings per hemisphere at polar angles of 49° and 59.5°. The 2D calculations with the hydrodynamics code FCI2 lead to a thermonuclear energy of 32 MJ with less than 1 MJ incident laser energy.
