摘　　要：描述了一台 2 .4 5GHz单电荷态电子回旋共振 (ECR)离子源的原理、结构与应用。介绍了其微波系统与磁场结构。在微波输入功率约 6 0 0W ,引出高压 2 2kV ,引出孔径为6mm时 ,该离子源的总束流I(H1++H2 ++H3+)可达 90mA。A 2.45GHz single charge state ECR ion source with permanent magnet has been developed at IMP. The physical principle and structure are presented, and the microwave system and magnetic configuration are introduced in this paper. A mixed ion (H 1 ++H 2 ++H 3 +) beam current of 90mA can be delivered from a single aperture of  6mm with microwave power of 600W at extraction voltage of 22kV.
