Open publisher page 0 citations

Abstract

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. 140uA of O~7+, 185uA of Ar~11+ and 50uA of Xe~26+ could be produced with a RF power of 800 W. 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 130uA of Ca~11+, 70uA of Ca~12+ and 65uA of Fe~lo+. The ion source has been put into operation for the cyclotron at the institute of Modern Physics (IMP).
