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.
