A method to assemble thermonuclear fuel for fast ignition with high densities, high , and a small size hot spot is presented. Massive cryogenic shells can be imploded with a low implosion velocity VI on a low adiabat using the relaxation-pulse technique. While the low VI yields a small hot spot, the low leads to large peak values of the density and areal density. It is shown that a 750-kJ laser can assemble fuel with cm/s, , g/cc, g/cm2, and hot-spot volume less than 10% of the compressed core. If ignited, this fuel assembly can produce yields up to of interest to IFE applications.
