Hydrodynamic models and schemes for fast ignition

In this paper, we want to discuss different hydrodynamic schemes for fast i gnition and some of their basic effects. Relativistic hydrodynamics and a c ovariant generalized Ohm's law are presented. Matter perforation (hole bori ng) by an intense laser pulse is investigated by 2D numerical simulations a nd a simple formula for the perforation speed is derived. Furthermore, we s tudy macroparticle acceleration by an intense laser beam and the possibilit y to provide an energetic and massive projectile for ballistic ignition. Th e dynamics of ignition of a precompressed D-T mixture is illustrated by num erical simulations in planar 2D geometry using direct laser irradiation and macroparticle impact as external drivers. Electron heat conduction is foun d to be responsible for an efficient burn wave propagation which prevents t he hot gas bubble of burning fuel from deflagrating into vacuum.
