Title: Dynamic Compression of Hydrogen and Other Small Molecular Fluids at High Pressures

Dynamic compression of molecular fluids using both single-shock (Hugoniot) and multiple-shock compression achieves pressures which range up to several Mbar (100 GPa), compressions up to ten-fold of ammore »bient liquid density, and temperatures up to several 1000 K in degenerate condensed matter. For several diatomic fluids, nonmetal-metal transitions determined by electrical conductivity measurements at densities achieved by multiple-shock compression and pressure-volume Hugoniot curves each have universal systematic behaviors. The extreme conditions are achieved for {approx} 100 ns using a two-stage light-gas gun, which accelerates a 20-g projectile to kinetic energies as high as 0.5 MJ. The systematics will be discussed, including the nonmetal-metal transition in fluid hydrogen at 1.4 Mbar and 10-fold compression and the controversial issue of the pressure-volume Hugoniot curve of deuterium near 100 GPa and 4-fold compression.« less
