压力，密度，温度，和反射率测量沿着的主要Hugoniot的锗掺杂的塑料在惯性约束聚变胶囊替代品获得的压力达到7兆巴，并比较了Quotidian状态方程模型。该实验是使用日本大坂大学激光工程研究所的GEKKO XII激光器进行的。使用石英标准获得了高精度的压力和密度测量，并发现与理论Hugoniot曲线吻合良好。反射率测量的建模表明，冲击样品可以被描述为贫穷的金属和QEOS的框架内计算的平均电离被高估。同样，冲击温度被发现低于理论Hugoniot曲线。
Pressure, density, temperature, and reflectivity measurements along the principal Hugoniot of Ge-doped plastics used in Inertial Confinement Fusion capsules surrogates were obtained to pressures reaching up to 7 Mbar and compared to Quotidian Equation of State models. The experiment was performed using the GEKKO XII laser at the Institute of Laser Engineering at Osaka University in Japan. High precision measurements of pressure and density were obtained using a quartz standard and found to be in good agreement with theoretical Hugoniot curves. Modeling of reflectivity measurements show that shocked samples can be described as poor metals and that mean ionization calculated within the frame of QEOS is overestimated. Similarly, shock temperatures were found to be below theoretical Hugoniot curves.
