ON TARGET DESIGN FOR HEAVY-ION ICF AND GAIN SCALING

First, gain scaling for ignition experiments recently published by the Livermore group is interpreted within the isobaric gain model. Secondly, two options for indirect drive of fusion targets with heavy-ion beams are compared, one having localized converter elements and the other using low-Z foam in the hohlraum for conversion. In addition, the new code MULTI2D for two-dimensional radiation hydrodynamics simulation is briefly discussed, and also progress in high-Z opacity calculations; both topics are relevant for future target work.
