An Electron Beam Ion Source Charge Breeder (EBIS-CB) has been developed at Argonne National Laboratory as part of the CAlifornium Rare Ion Breeder Upgrade (CARIBU). For the past year, the EBIS has been undergoing commissioning as part of the ATLAS accelerator complex. It has delivered both stable and radioactive beams with A/Q < 6, breeding times < 30 ms, low background contamination, and charge breeding efficiencies > 18% into a single charge state. The operation of this device, challenges during the commissioning phase, and future improvements will be discussed.
