Activities on target fabrication and injection toward laser fusion energy in Japan

Target-related activities to demonstrate ignition and burn were summarized. Fabrication of foam shells with a gas barrier by emulsion process, understanding of centering mechanism in the emulsion process, coating of organic photovoltaic cell to reduce initial imprint are described. Cooling-induced deformation (CID) of shells was studied and found to be important for thin shells. Results on magnetic levitation, injection and tracking that are necessary to provide targets to the firing position are mentioned
