The Beijing Radioactive Ion-beam Facility (BRIF) is one of the main projects at China Institute of Atomic Energy (CIAE), and will be a versatile platform for nuclear study in China. As a major part of this project, the 100 MeV cyclotron is designed to provide protons beam from 75 MeV to100 MeV continuously. In this paper, the seven beam transport lines are designed for different experiment application. Various aspects of the beam line design, e.g. the arrangement of the elements, beam optics, magnets, etc. are given in detail.
