Hydrogen Double-Shock Equation-of-State and Transport Data

ORAL

Abstract

We present findings of double-shock experiments in H2 and D2 where high-density, second-shock states were directly observed behind weak, transparent first shocks. A resulting shock merger is also observed. We deduce mechanical, thermal, and transport properties of the double-shocked D2 to pressures of 8 Mbar. These high-density states probe the transition of D2 from liquid metallic metal to classical plasma. Preliminary H2 data are also discussed. From these data we explore the off-Hugoniot behavior of D2 and H2 and conclude with a comparison of our findings to recent reshock experiments and models.
