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.
