Multiple-shock compression and optical/x-ray diagnostics of diamond in TPa pressure regime

ORAL

Abstract

We have performed multiple-shock compression experiments for diamond to TPa pressures. Optical diagnostics observed shock coalescence in the diamond layer and well-characterized the shocked diamond conditions ($P$, $V$, $T$). Noncollective x-ray scattering measurements for the shock compressed diamond have been performed for the first time. The ionized states of carbon in HED regime is indicated from the inelastic scattering components.
