At the frontiers of high-energy-density (HED) physics are the relatively recent studies of the properties of macroscopic amounts of matter at conditions where the energy density is very high, namely, where the energy/volume > 1012 erg/cm3. Such conditions correspond to matter at high density, high temperature or, in the case of electromagnetic radiation, high intensity. Such regimes can be created with high-power laser systems and on magnetic-pinch facilities and correspond to the conditions required for inertial-confinement fusion (ICF) and that occur naturally in many astrophysical systems. With the advent of modern, high-power lasers, studies in the HED regime have become possible and quite wide spread. The ability to shock and ramp-compress samples while simultaneously probing them allows us to study solid-state lattice dynamics and plastic flow relevant to planetary interiors. High temperature, high velocity interacting flows are being probed for evidence of astrophysical collisionless shock formation. This Lecture will present the recent results from the ICF program and other cutting-edge HED research projects at the National Ignition Facility at Lawrence Livermore National Laboratory, the largest laser system in the world.
