The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) is currently constructing its new reaccelerated beam facility- ReA3. ReA3 will provide unique low energy rare isotope beams by stopping fast, separated rare isotopes in different stopping systems, and then reaccelerating them in a linac. ReA3 will provide pioneering beams for research in one of the pillars of the next-generation rare isotope facility FRIB that will be hosted at MSU. The main components of ReA3 are a linear cryogenic gas cell to stop the fast beams produced by projectile fragmentation, an Electron Beam Ion Trap (EBIT) charge state booster, a compact accelerator using a room temperature RFQ and a superconducting linac using quarter wave resonators. An achromatic beam transport and distribution line towards the new experimental area will complete ReA3. Beams from ReA3 will range in energy from 0.3 to 6 MeV/u. The maximum energy is 3 MeV/u for heavy nuclei such as uranium, and 6 MeV/u for ions with A<50 as the charge state of the ions can be adjusted by the EBIT. The overall concept and status of ReA3 will be presented in particular emphasizing on the SRF-linac.
