“…4 it can be easily seen that other predictions of PPT in hydrogen or hydrogenhelium mixtures [2,30] with low mass concentration of helium are located in the beginning of the region where DPIMC simulation fails to converge. The sharp rise of electrical conductivity of hydrogen-helium mixture along the quasi-isentrope with the initial state T = 77.4 K and P = 8.1 · 10 − 3 GPa is also observed experimentally in the range of densities 0.5-0.83 g/cm 3 [35], see line with crosses in Fig. 4.…”

In this paper we study thermodynamic properties of hydrogen and hydrogen-helium mixtures with the help of the direct path integral Monte Carlo simulations. The results are compared with available theoretical and experimental methods based, in particular, on chemical picture. We investigate the effects of temperature ionization in low-density hydrogen plasma. We also present a number of calculated isotherms for hydrogenhelium mixture with the mass concentration of helium Y = 0.234 in the range from 10 4 K to 2 · 10 5 K. In the density region where a sharp conductivity rise have been observed experimentally the simulations give indications for one or two plasma phase transitions, in accordance with earlier theoretical predictions.

In this paper we study thermodynamic properties of hydrogen-helium mixtures with the help of direct Path-Integral Monte Carlo simulations. Presented are preliminary results of pressure and energy isotherms in the range from 10 4 K to 2 · 10 5 K in comparison with available theoretical and experimental results. In the density region, where experiments have observed a sharp conductivity rise the simulations yield indications for one or two plasma phase transitions, in accordance with earlier predictions.

“…Therefore, the multi-shock EOSs were usually obtained with the help of hydrodynamic simulations. [21][22][23] In this paper, we present results of the measurements of the Hugoniots of dense gaseous deuterium-helium (D 2 He) mixtures. A comprehensive diagnostic technique that combines multiple diagnostics enables us to implement (1) an accurate measurement of the single shock state of D 2 He mixtures, and (2) the direct measurements of multi-shock states.…”

“…There has been some creative multi-shock experiments were performed for hydrogen, 21 helium, 21,22 and hydrogen-helium mixtures. 23 In general, the multi-shock (more than twice) states are much more difficult to measure directly. Therefore, the multi-shock EOSs were usually obtained with the help of hydrodynamic simulations.…”

The accurate hydrodynamic description of an event or system that addresses the equations of state, phase transitions, dissociations, ionizations, and compressions, determines how materials respond to a wide range of physical environments. To understand dense matter behavior in extreme conditions requires the continual development of diagnostic methods for accurate measurements of the physical parameters. Here, we present a comprehensive diagnostic technique that comprises optical pyrometry, velocity interferometry, and time-resolved spectroscopy. This technique was applied to shock compression experiments of dense gaseous deuterium–helium mixtures driven via a two-stage light gas gun. The advantage of this approach lies in providing measurements of multiple physical parameters in a single experiment, such as light radiation histories, particle velocity profiles, and time-resolved spectra, which enables simultaneous measurements of shock velocity, particle velocity, pressure, density, and temperature and expands understanding of dense high pressure shock situations. The combination of multiple diagnostics also allows different experimental observables to be measured and cross-checked. Additionally, it implements an accurate measurement of the principal Hugoniots of deuterium−helium mixtures, which provides a benchmark for the impedance matching measurement technique.
