Abstract. We studied a variety of targets to be driven by ion beams or lasers in the past year. In order to relax target fabrication requirements, expand the allowed beam phase space volume and meet some radiological safety requirements, we continued to extend the set of the distributed radiator target designs for heavy ion beams. The hydrodynamic stability of a high gain directly driven laser target recently proposed at the Naval Research Laboratory has been studied. Because target chambers are sensitive to the x-ray spectrum as well as the composition and energy of the capsule debris we also present these for this target. A novel implosion scheme for the Fast Ignitor fusion scenario that minimizes the amount of coronal plasma that the igniting laser beam must penetrate is described. We describe recently derived scaling laws that relate the minimum value of the incoming fuel kinetic energy to the peak drive pressure, the fuel adiabat and the implosion velocity for capsules that use the kinetic energy of the implosion to heat the hotspot to ignition temperatures.
