Thermodynamic conditions of shock Hugoniot curves in hot dense matter

摘要

We use a self-consistent model combining the Quotidian Equation Of State and a nonrelativisticscreened-hydrogenic model with Q-splitting to study the thermodynamic conditions encountered alongshock Hugoniot curves. We focus on the maximum compression ratio reached on shock Hugoniot curvesfor simple elements that are solid at normal temperature and pressure. Electron shell effect and pressureionization can have a strong impact on the results. Numerical calculations are presented and discussed.Some of the physical points addressed in this work could be tested experimentally when the NationalIgnition Facility laser in the USA attains full power or when the Laser Megajoule in France comes online.
