Construction and installation of the Californium Rare Ion Breeder Upgrade (CARIBU) for ATLAS facility is nearly complete. The facility will use fission fragments from a 1 Ci 252Cf source, thermalized and collected into a low-energy particle beam by a helium gas catcher, mass analyzed by an isobar separator, and charge bred to higher charge states for acceleration in ATLAS. In addition, unaccelerated beams will be available for trap and laser probe studies. Expected yields of accelerated beams are up to ~5x105 (107 to traps) far-from-stability ions per second on target. We expect first beam tests from the project by May 2009. The facility design and first results of beam studies using a weaker 2.2 and 80 mCi sources will be presented in this report. Plans for installation of the 1 Ci source will be discussed.
