Reports that larger drivers, projected for the near future, are expected to compress the deuterium-tritium fuel to 1000 times its liquid density and achieve ignition of the fuel pellet. Vast amounts of fusion energy are released from the sun (and other stars) by natural thermonuclear processes that fuse atoms of lighter elements into atoms of heavier elements. In comparison to fission energy, fuel requirements for fusion energy are a factor of 50 less. Another advantage for fusion is that fuel supplies are more easily obtaineddeuterium from sea water and tritium from reactions with lithium. Describes the program being conducted in the US to develop inertial-confinement, as opposed to magnetic-confinement, fusion power. Discusses the physics of fusion. Presents a performance map that summarizes the operating conditions of some reaction chambers and indicates the major physical constraints on yield and background pressure that influence chamber design. The ranges of background pressure required for propagation of ion beams and lasers are also indicated, allowing a choice of viable driver and chamber combinations. Work on inertial fusion at UCLLL was performed under the auspices of the US DOE.
