Abstract
Laser-driven shock waves can generate very high-pressure conditions at high temperatures along the principal Hugoniot. Static compression of a material prior to dynamic shock-loading allows states at higher densities and lower temperatures to be accessed for a given pressure. We describe results from the first experiments to use diamond anvil cells (DAC) to pre-compress targets before laser-driven shock loading. Water was initially compressed in a DAC up to ~ 10 kbar and then irradiated using the Vulcan laser at Rutherford-Appleton Laboratory. Compared to states on the principal Hugoniot, the insulator-conductor transition in this off-Hugoniot regime was observed to occur at much higher pressures, shedding light on the nature of this transition.
