abstract = {{In the 3-GeV RCS (Rapid Cycling Synchrotron) of J-PARC (Japan Proton Accelerator Research Complex), multi-turn charge-exchange injection of H⁻ by using a thin stripper foil is performed to achieve high-intensity proton beam of 1 MW. The beam loss at 1 MW has already been well controlled, but for further minimizing both uncontrolled and controlled beam losses caused by the foil scattering of the circulating beam, recently we have implemented a lower vertical injection beam size and installed a corresponding smaller size stripper foil. A smaller foil gives a significant reduction of the foil scattering uncontrolled beam loss at the injection area, while an optimization of the vertical transverse painting area matching with a smaller beam size further gives an extremely reduction of the beam loss at the collimator section. The corresponding residual radiation at the recent operation with 700 kW beam power was also measured to extremely reduced.}},
