| 摘 要： | An ECR ion source for charge breeding of radioactive ions from the ISAC facility at TRIUMF has been set up at a test stand.It has been operated with different ion sources for the injection of singly charged ions and the efficiency,breeding time and emittance have been determined for several elements.A maximum efficiency of more than 6% for the breeding of Kr~(12 ) has been achieved so far.Additionally the charge exchange of Rb and Cs ions in the range of 10 to 23 with residual gas molecules in the transport beam lines has been investigated.The absolute values for the cross sections at 10—15 q keV agree with predictions extrapolated from lower charge states but the strong dependence on the ionization energy of the gas molecules could not be verified.
