Abstract ATLAS, the world's first accelerator to use RF superconductivity for ion acceleration, has undergone a major facility upgrade with the goals of significantly increased stable-beam current for experiments and improved transmission for all beams. The dominant components of the upgrade are a) new CW-RFQ to replace the first three low β resonators, b) a new cryostat of seven β=0.077 quarter-wave resonators demonstrating world-record accelerating fields, c) an improved cryogenics system, and d) the retirement of the original tandem injector. This latest upgrade followed closely on the earlier development of a cryostat of β=0.144 quarter-wave resonators. This reconfigured ATLAS system has been in operation for over one year. This paper will discuss the on-line performance achieved for the redesigned system, plans for further improvement, and long term facility plans for new performance capabilities.
