| Abstract |
In order to make a breakthrough in the conventional H⁻ charge-exchange injection done by using solid stripper foil, we proposed a completely new method H⁻ stripping to proton by using only lasers. Extremely high residual radiation due foil beam interaction beam losses as well as unreliable and short lifetime of the stripper foil are already serious issues in all existing high intensity proton machines. To established our new principle, experimental studies for a proof-of-principle (POP) demonstration at 400 MeV H⁻ beam energy is under preparation at J-PARC. A vacuum chamber for the POP demonstration has already been installed at the end section of 400 MeV H⁻ beam transport of J-PARC Linac. The H⁻ beam manipulations, numerical simulations as well as the laser beam studies are in progress. The present status of the POP demonstration of 400 MeV H⁻ stripping to protons by using only lasers are presented.
