| Outline of Final Research Achievements |
Laser intensity is continuously rising up because of the rapid progress of laser technologies. Various new world records can be realized by irradiating high-intensity laser pulse on a matter. We have challenged to generate strongest magnetic field on the earth with one of the world largest high-intensity laser facility called as LFEX at Institute of Laser Engineering in Osaka University. The high-intensity laser was irradiated on the inner surface of a tiny metal cylinder to drive a circular electric current along the surface of the cylinder, and the current generates a pulsed magnetic field in the cylinder. One of the LFEX laser beams was focused on a 300 micron-diameter cylinder to produce a magnetic field, and the other was focused on a planar foil to accelerate a proton beam to probe the magnetic field structure with the proton radiography scheme. We have achieved 2.3 kT of magnetic field strength, this is close to the largest magnetic field that was achieved on the earth.
