D₂Double Shock Equation of State and Transport Data

We present recent findings of double-shock experiments in D₂, where due to a transparent first shock, a second shock state is observed directly in addition to the resulting coalesced shock. We deduce mechanical, thermal, and transport, properties of the double-shocked material to pressures of several Mbar with reflectivity, shock velocity, and temperature data obtained from the VISAR (velocity interferometer system for any reflector) and the SOP (streaked optical pyrometer) diagnostics. From these data we explore the off-Hugoniot behavior of D₂ and conclude with a comparison of our findings to previous experiments, models, and off-Hugoniot techniques.
