Developing the numerical model for studying laser-compression of magnetized plasmas

摘要

The magneto-inertial (hybrid) approach to nuclear fusion is considered. Numerical simulation of radiation magneto-gas dynamic processes in the interaction of laser beams with a dense magnetized plasma (target) is created. A new quasi-monotone numerical method and model for laser driven implosion of magnetized target (laser driven magneto-inertial fusion) is proposed. Distinctive features of this problem are the presence of initial seed field (the imposed pulse magnetic field) and compression of a magnetic flux by laser beams (laser driver). The task for plasma formation and laser induced compression of magnetized target is formulated. Detailed numerical models of laser-driven magnetic flux compression and the pulsed high-temperature processes in two dimensions are developed.
