MSU/NSCL, East Lansing
The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) is currently constructing its new reaccelerated beam facility- ReA3. ReA3 will provide world-unique low energy rare isotope beams by stopping fast, separated rare isotopes in a gas-stopper, and then reaccelerating them in a Linear Accelerator. 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 the existing coupled cyclotron facility, an Electron Beam Ion Trap (EBIT) to boost their charge states, a compact accelerator using a room temperature RFQ and a superconducting linac, and an achromatic beam transport line for delivery to the new experimental area. 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. The overall design for ReA3 will be presented emphasizing on the ongoing construction and tests of its various components.
