  • Abstract
    An H0 injection system is proposed for the JHP compressor-stretcher ring. It is based on two-step stripping using a stripper magnet and a stripping foil. The H0 beam is formed to match the ring optics at the stripping foil. In order to reduce the foil hitting probability to as low as 10%, not only a corner foil, but also phase space painting by varying the bump orbit is proposed. In the latter case, the foil-hitting probability, estimated as the mean ratio of the beam area intercepted by the foil to the beam cross-sectional area weighted by instantaneous proton number, becomes as low as 8.3%
