摘　　要：简要介绍了低能辐照离子源的设计及性能。采用热阴极磁约束ＰＩＧ放电，并用两极多孔加减速系统引出离子束。调试结果：离子束能量在２００－２０００ｅＶ范围内可调，最大引出束流１５０ｍＡ，灯丝工作寿命１６０ｈ。The design and characteristics of a low energy irradiation ion source are presented.Magnetic field is used to maintain discharge plasma confinement.A two electrods system of acceleration and deceleration with many small holes is used to extract the ion beams.The results show that the energy of ion beam is between 200-2000eV,the maximum current of ion beams is 150mA and the working time of filaments is about 160h.
