    Development of 4.5 keV monochromatic X-ray radiography using the high-energy, picosecond LFEX laser 

    Sawada, H.; Fujioka, Shinsuke; Hosoda, T.; Zhang, Z.; Arikawa, Yasunobu; Nagatomo, Hideo; Nishimura, Hiroaki; Sunahara, A.; Theobald, W.; Patel, P. K.; Beg, F. N. (2016)
    Development of a monochromatic x-ray imaging system using a high-energy short-pulse laser LFEX and a spherical crystal is reported. Irradiation of the intense short-pulse laser produces a flash of 4.51 keV Ti K-alpha x-ray ...

    Direct heating of compressed core by ultra-intense laser 

    Sunahara, A.; Johzaki, Tomoyuki; Sakagami, H.; Nagatomo, Hideo; Mima, Kunioki; Abe, Yuki; Arikawa, Yasunobu; Fujioka, Shinsuke; Shiraga, H.; Azechi, Hiroshi; Mori, Y.; Sentoku, Y.; Kitagawa, Yoneyoshi (2016)
    We propose a new scheme for heating an imploded core in the fast-ignition scheme. In this method, a heating laser irradiates an imploded core plasma directly. The accelerated fast-ions as well as fast-electrons heat the ...

    Electron beam guiding by external magnetic fields in imploded fuel plasma 

    Johzaki, Tomoyuki; Sentoku, Y.; Nagatomo, Hideo; Sunahara, A.; Sakagami, H.; Fujioka, Shinsuke; Nagatomo, Hideo; Endo, T. (2016)
    For enhancing the core heating efficiency in fast ignition laser fusion, we proposed the fast electron beam by externally-applied the kilo-tesla (kT) class longitudinal magnetic field. We evaluated the imploded core and ...

    Magnetized fast isochoric laser heating for efficient creation of ultra-high-energy-density states 

    Sakata, Shohei; Lee, Seungho; Morita, Hiroki; Johzaki, Tomoyuki; Sawada, Hiroshi; Iwasa, Yuki; Matsuo, Kazuki; Law, King F. F.; Yao, Akira; Hata, Masayasu; Sunahara, Atsushi; Kojima, Sadaoki; Abe, Yuki; Kishimoto, Hidetaka; Syuhada, Aneez; Shiroto, Takashi; Morace, Alessio; Yogo, Akifumi; Iwata, Natsumi; Nakai, Mitsuo; Sakagami, Hitoshi; Ozaki, Tetsuo; Yamanoi, Kohei; Norimatsu, Takayoshi; Nakata, Yoshiki; Tokita, Shigeki; Miyanaga, Noriaki; Kawanaka, Junji; Shiraga, Hiroyuki; Mima, Kunioki; Nishimura, Hiroaki; Bailly-Grandvaux, Mathieu; Santos, Joao J.; Nagatomo, Hideo; Azechi, Hiroshi; Kodama, Ryosuke; Arikawa, Yasunobu; Sentoku, Yasuhiko; Fujioka, Shinsuke (2018)
    Fast isochoric heating of a pre-compressed plasma core with a high-intensity short-pulse laser is an attractive and alternative approach to create ultra-high-energy-density states like those found in inertial confinement ...

    Study of fast electron generation using multi beam of LFEX-class laser 

    Hata, Masayasu; Sakagami, H.; Johzaki, Tomoyuki; Sentoku, Y.; Nagatomo, Hideo (2016)
    Fast Ignition Realization Experiment project phase-I (FIREX-I) is being performed at Institute of Laser Engineering, Osaka University. In this project, the four-beam bundled high-energy Petawatt laser (LFEX) is being ...
