<jats:p>Scaling relations to optimize implosion parameters for fast-ignition inertial confinement fusion are derived and used to design high-gain fast-ignition targets. A method to assemble thermonuclear fuel at high densities, high ρR, and with a small-size hot spot is presented. Massive cryogenic shells can be imploded with a low implosion velocity VI on a low adiabat α using the relaxation-pulse technique. While the low VI yields a small hot spot, the low α leads to large peak values of the density and areal density. It is shown that a 750kJ laser can assemble fuel with VI≃1.7×107cm∕s, α≃0.7, ρ≃400g∕cc, ρR≃3g∕cm2, and a hot-spot volume of less than 10% of the compressed core.
