| Outline of Final Research Achievements |
In interactions between ultra-intense laser beams and matters, radiation reaction effect plays an important role. In this regime, it was shown that high density gamma-rays are generated by laser-plasma interactions. In this project, we developed new particle code which realizes consistent analyses from laser-plasma interaction to gamma-ray transport in matters. We used Particle-in-Cell algorithm to solve the both laser-plasma interaction and gamma-ray generation via radiation reaction effect. The gamma-ray transport processes are modelled by using Monte-Carlo method. The developed code is benchmarked by using Particle and Heavy Ion Transport code System (PHITS). By using our code, we have shown that very energetic positron beams are generated from laser-plasmas, which could open a possibility of laser-driven positron source.
