Shock ignition, an alternative concept for igniting thermonuclear fuel, is explored as a new approach to high gain, inertial confinement fusion targets for the National Ignition Facility (NIF). Results indicate thermonuclear yields of approx120-250 MJ may be possible with laser drive energies of 1-1.6 MJ, while gains of approx50 may still be achievable at only approx0.2 MJ drive energy. The scaling of NIF energy gain with laser energy is found to be Gapprox126E (MJ){sup 0.510}. This offers the potential for high-gain targets that may lead to smaller, more economic fusion power reactors and a cheaper fusion energy development path.
