The multi-TW laser system "JLITE-X (JAEA Laser system for laser-matter InTeraction Experiment)" was developed for studying on the laser-matter interaction in sub-relativistic regime. Two quasi-monoenergetic charged particle production experiments were conducted after laser system development. The first, we successfully generated quasi-monoenergetic proton beam by using phase rotator which based on the radio-frequency accelerator technique. The quasi-monoenergetic component was observed near 600 keV with 1 TW / 220 fs laser operation mode. The second, we also successfully generated quasi-monoenergetic electron beam with energy of 20 MeV in self-modulated laser-wakefield regime with 3 TW / 70 fs operation mode. These results were indicated that the multi-TW laser is useful for not only plasma physics research but also high-energy particle source and its applications.
