【摘要】 叙述了兰州近代物理研究所的在线同位素分离器FEBIAD源的设计原理、结构、运行状况及离线和在线调试结果。离线测定Kr和Xe的总效率分别为 3.1%和 4 .5% ,12 9Xe分辨本领达到36 0 ,离子源总离子束流小于 10 μA。在线测到截面为 10 - 2 8cm2 、寿命短至 1s的反应产物 ,在线测出10 4 In总效率达到 1.5%— 2 % ,10 4 Ag和10 4 Gd达到 1%。更多还原

【Abstract】 The design principle, structure and operation performance of the FEBIAD target ion source were described. The off-line overall efficiencies are 3.1% for Krypton and 4.5% for Xenon, the total ion current being less than 10μA. The on-line overall efficiencies are 1.5%—2.0% for 104 In and 1% for 104 Ag and 104 Gd.更多还原
