摘　　要：叙述了在复旦大学加速器实验室３０ｋｅＶ同位素分离器上建立的一套离子注入装置。在该装置上已获得几十微安的Ｙ、Ｃｅ、Ｈｏ、Ｓｍ、Ｎｄ、Ｌａ、Ｙｂ等稀土离子束流。被离子注入的面积为φ２０ｍｍ，表面均匀性好于３％，并对Ｙ离子注入不锈钢以改善其抗腐蚀性能进行了初步研究．An ion implantation system based on a 30 keV mini-separator has been set up and tested at Fudan University. With the system up to some ten μA/cm2 of ion beam current of rare-earth elements such as Y, Ce, Ho, La, Sm, Nd and Yb, have been obtained. The modification of corrosion resistance for an Y ion implanted stainless steel sample has also been investigated.
