Abstract：
A compact 2.45GHz electron cyclotron resonance ion source (ECRIS) for high beam current of single charge state has been nuilt at Institute of Modern Physics. A mixed ion (H1+H2+H3) beam current of 90mA is delivered from a single aperture of φ6mm with rf power 600W at extraction voltage 22kV. This paper introduces the source structure, the magnetic configuration, the test results and the relation between the magnetic configuration and total beam current. In addition, the magnetic configuration is also compared with that of the other 2.45GHz ECR ion scarces built in different laboratories. Finally, some conclusions are presented.
