Proposal for a radioactive nuclear beam facility at CIAE

The proposal for a radioactive nuclear beam facility at CIAE is based on the present HI-13 tandem accelerator. A new intensity proton cyclotron accelerator will be built to provide a primary proton beam with 70 MeV, 200 μA. A thick target-ion source system and an on-line isotope mass separator system will produce the interesting exotic radioactive nuclear beam. The beam then passes through a charge exchange canal to change its charge state to negative ion and is injected into the present HI-13 tandem. A super conducting heavy ion linac accelerator will be built as a post accelerator, which can give an energy gain of 17 MeV/q. A 5 MeV/A radioactive exotic ion beam with an intensity of more than 6 × 108 p.p.s for masses up to A = 130 will be expected with this facility.
