The National Superconducting Cyclotron Laboratory at Michigan State University is a Radioactive Ion Beam (RIB) facility providing beams of exotic nuclear species through projectile fragmentation. The Coupled Cyclotron Facility accelerates stable ion beams to ~100 MeV/A which are then fragmented and selected with the A1900 separator. A recent addition to NSCL is the gas stopping facility which thermalizes the high energy beam. The RIBs are extracted at <60keV and selected by A/Q for further transport to the low energy areas, currently consisting of the BECOLA beam cooling and laser spectroscopy system, and LEBIT Penning trap. RIBs up to 6 MeV/A will be provided by the ReA post-accelerator, currently consisting of an EBIT, RFQ and superconducting RF cavities. Energies up to 1.5 MeV/A are presently available, and energy increases will be phased in with the addition of further cryomodules. In a campaign of commissioning experiments, RIBs from a fragmentation facility were thermalized and post-accelerated for the first time. Preliminary results will be presented, focussing on the diagnostic challenges of detecting and characterizing beams over a wide range of energy and rate.
