| Abstract |
Multi-turn charge-exchange beam injection is key technique to achieve the high intensity proton beam accelerators. In the J-PARC RCS, 400MeV H⁻ beams from the LINAC are converted to H⁺ beam with the stripper foils, and then injected into the ring. The stripper foil is irradiated by not only the injecting H⁻ beams but also the circulating H⁺ beams. The high energy and high power beam irradiation into the foil induces the nuclear reactions, and generated secondary neutrons and protons. These secondary particles causes high residual does around the stripper foil. Now, to identify species of secondary particles and to identify energies and emission angles, activation analysis method using the sample pieces is considered. In this presentation, we report the result of the evaluation of this activation analysis with PHITS codes.
