Abstract
We have tested a scheme for using laser implosion plasmas to generate pressures in the gigabar (100 TPa) regime. Cone-in-shell targets employed in fast ignition of inertial confinement fusion were irradiated to create a high-pressure source for compression of materials. The imploded plasmas pushed a foil embedded on the tip of a cone. The pressure was estimated from the shock velocity into the material; the shock velocity was obtained from an optical measurement. The measured shock velocity of the foil was above 100 km/s, corresponding to a pressure greater than 1 Gbar.
