Brookhaven National Laboratory (BNL), located on Long Island, New York, intends to competitively award a firm-fixed-price contract for the fabrication of a QCT Cabin for the NSLS-II beamline. The cabin will be constructed at the 16-BM location on the existing experimental floor and will serve as an enclosure and interface for experimental operations, equipment housing, samples testing, and user analysis. One award is expected under full and open competition. Performance will be at Brookhaven National Laboratory. The anticipated award date is on or around April 15, 2027.
