The high intensity cyclotron CYCIAE-100 adopts the stripping foil to extract the proton beam with energy of 75-100 MeV. Because of the large energy range of the extracted beam, the combination magnet should be placed at the extracting port to concentrate the beam with different energies along a common The high intensity cyclotron CYCIAE-100 adopts the stripping foil to extract the proton beam with energy of 75-100 MeV.
