Theory and modeling of ion acceleration from the interaction of ultra-intense lasers with solid density targets

The interaction of a high intensity, short-pulse laser with a thin target can lead to the generation of a highly collimated beam of fast ions off the rear target surface. These ion beams have the potential to impact inertial confinement fusion applications, including their use in diagnostics and fast-ignition. Recent work by the authors in the modeling of ion acceleration, using both full particle-in-cell and hybrid (particle ions, reduced electron physics) models, is leading to improved understanding of the physics governing ion acceleration
