Description
The Argonne Tandem Linac Accelerator System (ATLAS) continues to receive requests for increasing beam intensities, energies, species, and time on target. Over the past few years, most of the ion beams delivered to experiments have been produced by the two ATLAS Electron Cyclotron Resonance Ion Sources (ECRIS), ECR2 and ECR3. While demands increase, the ATLAS team continues to make improvements and upgrade subsystems to expand beam capabilities. An infrastructure upgrade for cooling water has increased the operating range of the ECR2 solenoids, leading to an improved 136Xe28+ intensity of 24 euA as compared to the previous best of 15 euA. The ATLAS Multi-User Upgrade (AMUU) project will allow simultaneous delivery of beams from the ECR2 and the Electron Beam Ion Source (EBIS) to separate experiments. The front-end feasibility has been demonstrated with the interleaving of a 10 enA 84Kr17+ beam from the ECR2 and a 100 epA 133Cs27+ beam from the EBIS with subsequent acceleration through the PII and Booster linacs. Lastly, ECR3 now has the capability of producing tritium (3H) ion beams and has successfully delivered its first tritium beam to an experiment. Details of these improvements are presented.
