§3. Development of Cryostat for Fast Ignition Experiments Norimatsu, T., Shiraga, H., Nakai, M., Nagai, K. OLE, Osaka Univ.), Sakagami, Y., Yoshida, H., (Gifu Univ.), Mito, Y. At ILE, Osaka University, the FIREX (Fast Ignition Realization Experiment) project has been conducted to demonstrate heating of a compressed core to 5 ke V using a several PW laser pulse from the Gekko laser. In 2003, development of the FI (fast ignition) target with a reentrant cone and a gas feeder pipe was started at ILE and development of the cryostat and the characterization technique is studied at Purpose \PW Heat i ng leser 1 kJ/l ps Compression laser Implosion experiment (Coleb) of cryogenic target RI control Shell development Flat taget Proof of principle of foam method Character ization Cryostat for 00 experiment New cryostat for DT {NIFS) experiment NIFS. Implosion experiment of the cryogenic target will be conducted on collaboration of ILE and NIFS. Figure IL is the time schedule toward heating of compressed core up to 5ke V. Main achievement in 2003 was development of a 5-j.!m-diameter gas feeder pipe to minimize the influence on the implosion symmetry and fabrication of low density foam to support a cryogemc fuel layer. Resorcinol formaldehyde (RF) foam was chosen for the foam material because of its high transmittance of visible right which can allow optical characterization of the cryogenic layer. Figure I IS a timetable for the project. A polystyrene shell target with the gas feeder and the reentrant cone is also shown.
