Production of Ion Beams of Radioactive Aluminum Isotopes at BRISOL Facility

Isotope separator on-line of Beijing radioactive ion-beam facility (BRISOL) produces medium and short-lived radioactive isotope beams by irradiating targets with a maxium 200 µA proton beam from a 100 MeV cyclotron. Na and K radioactive ion beams(RIBs) have been generated with CaO and MgO targets at BRISOL. Recentely Al RIB is produced with a SiC target, the beam intensity of ^26gAl⁺ and ²³Al⁺ is 8.7×10⁷ pps and 2.2×10² pps respectively. The SiC target can endure 15 µA proton beam. In this paper, the development of SiC targets and the results of AL RIB on-line production are presented.
