Outline of Final Research Achievements

For the lifetime evaluation of the beam window used for high-intensity accelerators such as J-PARC center, a nuclide production cross section of an aluminum and a gas production cross section of carbon were measured.
The experiment carried out by using 3-GeV proton accelerator of the J-PARC center. Owing to well-calibrated beam monitors and a precise beam control system, we obtained accuracy experimental data than those of previous experimental ones. The present experimental results were compared with the nuclear calculation model aimed to be improved the model.
