Emission measurements from laser-driven shocks propagating in planar deuterium targets.
Abstract
Properties of deuterium at high pressure and density are important in astrophysics, inertial confinement fusion, and condensed matter physics. We will present initial experimental results on time-resolved light emission from shock breakout from an aluminum pusher into liquid deuterium. As the shock begins to propagate into the deuterium, the emission signal evolves from characterizing the hot aluminum to a state that is primarily characteristic of the shocked deuterium. Measurements of this transition time are expected to give us information about the conductivity and optical depth of the shocked deuterium. Measurements are preformed using a streak camera at up to 2ps time resolution on targets driven by the Nike KrF laser. In addition, we will present spatially resolved measurements of shock temperature using the absolute emission data and emissivity values obtained from the reflectivity measurements.
