The project of Beijing Radioactivity Ion-beam Facility (BRIF) is being constructed at CIAE. As a major part of the BRIF project, the 100 MeV compact cyclotron (CYCIAE-100) will provide proton beam with an intensity of 200-500 μA. The extracted proton energy range is 75-100 MeV with the carbon foil stripping system. The stripping probe system is the major part of the extraction system for CYCIAE-100, The project of Beijing Radioactivity Ion-beam Facility (BRIF) is being constructed at CIAE.
