| Outline of Final Research Achievements |
The project aims, by utilizing the advanced ion acceleration method with the use of micron-size cluster targets developed by PI and co-workers, to find a new way to generate quasi-monoenergetic ion beams exceeding 100 MeV, which has a potential to be widely applicable to medical and industrial purposes, but no one has accomplished before. In numerical studies using the 3D-PIC code, we have discovered a new approach for accelerating a quasimonoenergetic proton bunch up to 290 MeV via a hemispherically converging collisionless shock created via laser-cluster interactions at the relativistically induced transparency regime. We have conducted ion acceleration experiments with the PW class J-KAREN-P laser at QST-KPSI. We found that only protons having the energies exceeding 10 MeV were for the first time accelerated in the forward direction with a high repetition rate.
