Hugoniot Measurements of Silicon Shock Compressed to 25 Mbar
ORAL
Abstract
We present results of laser-driven shock experiments that compressed silicon samples to 25 Mbar. Impedance matching to a quartz reference provided Hugoniot data. Since silicon is opaque, a quartz witness was placed adjacent to the silicon samples; this afforded the use of the unsteady wave correction\cite{Fratanduono:1}to increase the precision of the transit-time measurements of shock velocity. Results are compared with both \textit{SESAME} tables and quantum molecular dynamics calculations. This material is based upon work supported by the Department Of Energy National Nuclear Security Administration under Award Number DENA0001944. D. E. Fratanduono \textit{et al}., J. Appl. Phys. \textbf{116}, 033517 (2104).
