Description
Beijing Radioactive Ion-beam Facility (BRIF) at China Institute of Atom Energy (CIAE) utilizes the high intensity proton beam extracted from a 100 MeV cyclotron to produce the radioactive ion beams (RIB) by the isotope separation on-line method. A positive surface ionization source has been developed to produce the first radioactive ion beam. The modulation design was under development to fullfill the strict requirements of high voltage insulation, radioactive damage, vacuum and cooling water seal, and so on. The ion source was tested with $^{7}$Li$^{+}$ and $^{39}$K$^{+}$ stable beams. Also $^{38}$K$^{+}$ radioactive beam was produced by bombarding CaO target by 100 MeV proton beam. The designing and the current status of the target/ion source will be presented.
