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%,129Xe分辨本领达到360，离子源总离子束流小于10μA。在线测到截面为10-28cm2、寿命短至1s的反应产物,在线测出104In总效率达到1.5%—2%,104Ag和104Gd达到1%。%The design principle，structure and operation performance of theFEBIAD 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 104In and 1% for 104Ag and 104Gd.
