A shock impedance match experiment was performed in close proximity to an underground nuclear explosion. A shock wave travelled through Al(alloy 1100) into Mo and the shock velocities were measured in each. Relative to an equation of state for Al calculated from pseudopotential theory the pressures achieved were 1.37 and 2.50 TPa in Al and Mo, respectively. Double-shock experiments were also performed for Al using a two-stage light-gas gun. Effective Grueneisen parameters were found to agree with constant ..gamma../V scaling.
