Abstract：
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 Kr¹²⁺ 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.
