	The Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU) is currently in the preliminary design phase. FRIB consists of a heavy ion driver LINAC, followed by a fragmentation target station, and a ReAccelerator facility (RεA). In its final configuration, RεA will provide heavy ion beams from 0.3 MeV/u to 12 MeV/u for heaviest ions and up to 20 MeV/u for light ions. While FRIB plans to start conventional construction in 2012, the first stage of RεA is already under commissioning and will be connected to the Coupled Cyclotron Facility at MSU end of 2012. The front end of the accelerator consists of a gas stopper, an Electron Beam Ion Trap (EBIT) charge state booster, a room temperature RFQ, followed by a short SRF LINAC, which contains seven β=0.041, eight β=0.085 QWR cavities, and eight 9T focusing solenoids. RεA serves as prototyping test bed for the FRIB cryomodule development since FRIB utilizes similar cavities as installed on RεA. An overview and status of the RεA facility will be presented. The presentation will focus on the testing, beam commissioning, and operational experience of the first β=0.041 cryomodules.
