An ISOL test-bench at China Institute of Atomic Energy

An isotope separation on-line (ISOL) test-bench has been built at China Institute of Atomic Energy, an electron beam plasma type target/ion source selected as the ion source of the system. By bombarding selected targets with a proton beam from the HV-13 tandem, low intensity radioactive ion beam can be produced on-line. The first planned ion species is 62Zn+ and it will be used as nuclear probe to investigate the character of solid material by perturbed angular correlation and positive electron annihilation methods. Off-line tests are being carried out. The character of the target ion source and copper target to be used is described in this paper. Finally, a brief introduction of the ISOL design for the Beijing radioactive nuclear beam facility will be given.
