Abstract
An impact scheme of a slab target and flyer with a layered structure is pro posed to achieve low-entropy dynamic compression of diamond. The thermodyna mic state of diamond during compression is examined using one-dimensional L agrangian hydrodynamic code and the tabulated equation of state library, SE SAME. The use of a material with a small shock impedance for the impact int erfaces markedly decreases the strength of the primary shock wave. It is fo und that a gradient of shock impedance across the thickness of the flyer ge nerates small multiple shock waves into the diamond and is effective for lo w-entropy compression. The thermodynamic conditions required for carbon sim ple cubic and low-entropy dynamic compression is achieved.
