Next steps for target technology and power plant design

Current activity at ILE Osaka on fabrication of fast ignition targets toward laser fusion reactor will be discussed. The issue includes fabrication of low density foam shell to form a solid fuel layer, machining of the foam shell to assemble a reentrant cone, fabrication of the cone as a laser focusing device and fuel loading in the future mass production process. We are going to present a new idea for the fuel loading, which would enable us to fill the fuel accurately in short time without any feedback control system. Tritium inventory in the target factory will be reduced to be <1/10 of that by conventional diffusion fill. (author)
