The Beam Gas Ionisation (BGI) instrument of the Proton Synchrotron (PS), presently installed and operational, has been re-designed for the Super Proton Synchrotron (SPS), the following machine along the Large Hadron Collider (LHC) injector chain at CERN accelerator complex. Using the same detection technology, Timepix3, the SPS-BGI infers the beam profile from the electrons created by the ionisation of rest gas molecules and accelerated onto an imaging detector. This measurement method will allow for continuous, non-destructive beam size measurement in the SPS. In view of the upgrade, the design has been simplified and validated for integration, radio-frequency & impedance, high-voltage and ultra-high vacuum compatibility.

Stripper foil is a key equipment for converting negative hydrogen ions into protons in the RCS injection zone of CSNS. The structure of the CSNS primary stripper foil adopts a rotating steel strip structure, and the replacement time of the foil is long, requiring operators to carry out maintenance work in close proximity for a long time. The energy of CSNS-II injection beam has significantly increased from 80MeV to 300MeV, and the radiation dose in the injection area will also increase, making it impossible to maintain the equipment in close proximity for a long time. Therefore, it is necessary to redesign the primary stripper foil. This article will analyze the stripper efficiency and beam injection thermodynamics of CSNS-II stripper foil, carry out automatic foil store replacement structure design, motion analysis, and prototype testing, and envision remote maintenance solutions to achieve maintenance and repair of the stripper foil with minimal human intervention.
