摘　　要：介绍了一台２．４５ＧＨｚ电子回旋共振（ＥＣＲ）单电荷离子源的磁场场形，以及它和总束流的关系．并且比较了国际上现有的几台同类型离子源的磁场场形．由此得出了关于２．４５ＧＨｚＥＣＲ离子源磁场场形的一些结论．A compact 2.45GHz electron cyclotron resonance ion source(ECRIS) for high beam current of single charge state has been nuilt atInstitute of Modern Physics. A mixed ion (H1+H2+H3) beam current of90mA is delivered from a single aperture of 6mm with rf power 600W atextraction voltage 22kV. This paper introduces the source structure, themagnetic configuration, the test results and the relation between the magneticconfiguration and total beam current. In addition, the magnetic configurationis also compared with that of the other 2.45GHz ECR ion scarces built indifferent laboratories. Finally, some conclusions are presented.
