High-intensity laser and thin-foil interactions produce high-energy particles and hard X-ray. A proton beam driven by a high-intensity laser has received attention as a ion source for medical and other applications. We have performed high energy laser-matter interaction experiments using a thin-foil target irradiated by LFEX laser at Osaka University. The three beams were focused at a thin-foil target. The maximum proton energy of 40 MeV energy were observed at the total laser energy of 1 kJ. The proton acceleration experiment with plasma mirror are started.
