BRISOL铝同位素放射性核束的产生

Production of Ion Beams of Radioactive Aluminum Isotopes at BRISOL Facility

  • 摘要: 北京放射性核束装置在线同位素分离器(BRISOL)采用100 MeV回旋加速器提供的最大200 μA的质子束打靶在线产生放射性核束。在BRISOL上已经使用氧化钙靶、氧化镁靶产生了Na+、K+等放射性核束。为了产生铝同位素放射性核束,研发了碳化硅靶材,开展了碳化硅靶产生铝放射性核束的实验研究。在BRISOL装置上首次产生了铝同位素放射性核束,其中26gAl+的束流强度为8.7×107 pps,23Al+的束流强度为2.2×102 pps,同时将BRISOL靶能承受的质子束流强提升至15 。

     

    Abstract: 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.
