Abstract
Coupling laser-shock and static-compression techniques allows to generate material conditions unreachable by either single-shock or static technique alone. Static compression experiments on water were performed using a precompression cell for laser-driven shock experiments. The pressure on static compression in this work was reproductively 1.3 – 2.3 times higher than in previous works and theoretical predictions. We have also performed static compression experiments using a new anvil material (Gd3Ga5O12) to apply the cell to reflected shock compression. By coupling laser-driven reflected shock compression with precompression technique, it is possible to generate higher pressure and lower temperature range.
