Regimes of Heating and Compression in Magneto-Inertial Fusion
Resumo
Simulation models of ignition and burn for magnetized fuel target compressed by high pulse energy lasers (laser driver) and high velocity plasma guns (plasma liner) are presented. An improved radiationhydrodynamics code FUCUS (Fusion bUrn in targets under Compression nUmerical Simulation) which simulates plasmas in cylindrical or spherical geometries is created. Numerical method to determine parameters and regimes in a mathematical model of magnetized target plasma compression and heating is described. Models for high pulse energy laser, high speed plasma jets and magnetic field are presented. The method of quasi-mechanical analogy is used to build the regular adaptive grid. Different regimes in the target for magneto-inertial fusion are considered. The effect of external magnetic field on the radiation-magnetic hydrodynamic instabilities is discussed.
