【Abstract】 The layout of Xi’an 200 MeV Proton Application Facility(XiPAF) vacuum system is introduced. The beam loss caused by residual gas in vacuum is analyzed, and the actual vacuum distribution along the beam line is modeled by the VAKTRAK codes. The analysis and calculation results show that the vacuum distribution on XiPAF synchronous ring is relatively uniform, and the overall vacuum design meets the requirements. The dedicated vacuum chambers and vacuum joints are introduced, and the operation of XiPAF vacuum system is described. The results show that the vacuum system runs well and can meet the requirements of beam operation.更多还原
