Hugoniot measurement of gold at high pressures of up to 580 GPa

Hugoniot for Au was measured over a pressure range from 190 to 580 GPa using a two-stage light-gas gun. The accuracy for impactor velocity was 0.2% and that for shock velocity ranged from 1.0% to 2.3%. Symmetric-impact experiments were performed to obtain shock compression data that are independent...

Description
Summary:Hugoniot for Au was measured over a pressure range from 190 to 580 GPa using a two-stage light-gas gun. The accuracy for impactor velocity was 0.2% and that for shock velocity ranged from 1.0% to 2.3%. Symmetric-impact experiments were performed to obtain shock compression data that are independent of those of other materials. The relationship between the shock and the particle velocity shows that our data for shock velocity deviate upward from the previously established relationship by up to 2.7% at u p = 3.5 km ∕ s . Moreover, we also report data obtained by impedance matching using Ta and Cu.
