    Abstract
  • Shock temperature of liquid argon has been measured under the shock pressure up to 33 GPa by employing the two-stage light gas gun. Impactor velocities were measured with electrical-magnetic induction system. Shock velocities and shock temperature of liquid argon were measured by using optical-fiber pyrometer. Mass velocities were obtained by mean of shock impendence matching method. The experimental data shows that shock temperature reach 10 000 K at 33 GPa shock pressure. Over 30 GPa shock pressure, shock temperature is lower compared with theoretical data. The experimental data also shows that the slope of shock temperature-shock volume curve begins to decrease over 30 GPa, which is the same shock pressure as the previously published shock Hugoniot curve.
