Direct-drive inertial confinement fusion (ICF) creates extreme states of matter. In current direct-drive cryogenic implosions on the 60-beam OMEGA laser system, the compressed target has a measured pressure of 5 Gbar. These targets are hydrodynamically scaled from ignition targets for the National Ignition Facility. This paper reports on our recent experiments, progress in validating the hydrodynamics codes that are used to design future high-gain cryogenic targets, and techniques to improve target performance. A brief description is given of a new high energy petawatt laser - OMEGA EP (extended performance) - that is being added to the OMEGA compression facility.
