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. Second ly, two options for indirect drive of fusion targets with heavy-ion be ams are compared, one having localized converter elements and the othe r using low-Z foam in the hohlraum for conversion. In addition, the ne w 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.
