Off-Hugoniot measurements for alpha-quartz

ORAL

Abstract

In order to accurately obtain unknown material's EOS, off-Hugoniot information of standard material, including re-shock and release isentrope, is required. For this purpose, we performed sapphire EOS measurements with using quartz base, obtaining new sapphire data in TPa (10 Mbar) pressure regime. Moreover, a novel experimental scheme will be discussed to accurately determine quartz release curve for low-density, soft materials EOS experiments.
