【Abstract】 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.更多还原
