A new 14.5 GHz Electron Cyclotron Resonance (ECR) ion source has been constructed over the last two years. The source was designed and tested by making use of the latest results from ECR ion source development, such as high mirror magnetic field, large plasma volume, and biased probe. 140µA of O7+, 185µA of Ar¹¹⁺ and 50µA of Xe²⁶⁺ could be produced with a RF power of 800W. The intense beams of highly charged metallic ions are produced by means of the method of a metal evaporation oven and volatile compound through axial access. The test results are 130μA of Ca¹¹⁺, 70µA of Ca¹²⁺ and 65µA of Fe¹⁰⁺. The ion source has been put into operation for the cyclotron at the Institute of Modern Physics (IMP).
