Design & construction status of CYCIAE-100, a 100 MeV H− cyclotron for RIB production

For productions of intense proton and radioactive ion beam (RIB) used in fundamental and applied research, e.g. neutron physics, nuclear structure, material and life sciences and medical isotope production, a new RIB facility, Beijing radioactive ion-beam facility (BRIF) had been started at CIAE since 2004. In this project, a 100 MeV H− cyclotron is selected as the driving accelerator. It will provide a 75-100 MeV, 200-500 μA proton beam. In this paper, BRIF will be described briefly. Then, various aspects about the 100 MeV cyclotron including the general description, specification, beam dynamics, design and construction status of the magnet, RF system etc. will be described respectively. And some R&D, including the CRM (Central Region Model) cyclotron, LLRF control, 10 mA H− source etc. for this machine will also be illustrated in this paper.
