Description
During the injection process, after the foil stripping, the remaining particles are H−, H0, p and e−. The injection system must promise that most of the H− particles are stripped to protons and enter the RCS. Although the residual particles H−, H0 and e− are relatively small, they can cause beam instability and large beam losses if left untreated. In this paper, for the CSNS-II, the treatment of the residual particles after foil stripping will be studied in detail. The little H0 particles, stripped by the secondary stripping foil, enter the beam dump. The very small amount of un-stripped H− particles are deflected by the magnet BCH3 and enter another beam dump. The stripped electrons will be collected by an electron catcher.
