Research Abstract

This research numerically makes it clear that Carbon Simple Cubic is able to be generated thermodynamically by the dynamic compression of the impact at the collision between the target and flyer which is accelerated by the laser ablation pressure. The Carbon Simple Cubic is expected to appear at the pressure more than 2 Tpa, however it may melt with the temperature of more than several 1000 K. An impact scheme of a slab target and flyer with a layered structure is proposed to achieve low-entropy dynamic compression starting from diamond. The thermodynamic state of diamond during compression is examined using one-dimensional Lagrangian hydrodynamic code and the tabulated equation of state library SESAME. The use of a material with a small shock impedance for the impact interfaces markedly decreases the strength of the primary shock wave. It is found that a gradient of shock impedance across the thickness of the flyer generates small multiple shock waves into the diamond and effective for low-entropy compression. The thermodynamic conditions required for Carbon Simple Cubic and low-entropy dynamic compression is achived.
