Title: Measurement of the adiabatic index in Be compressed by counterpropagating shocks

Abstract

Here, we report on the first direct measurement of the adiabatic index through x-ray Thomson scattering from shock-compressed beryllium. 9 keV x-ray photons probe the bulk properties of matter during the collision of two counterpropagating shocks. This novel experimental technique determines by using only the measured mass densities and vanishing particle velocity at the point of shock collision to close the Rankine-Hugoniot equations. We find γ > 5/3 at 3x compression, clearly different from ideal gas behavior. At 6x compression, shows the convergence to the ideal gas limit, in agreement with linear scaling laws.
