The Department of Energy, through Brookhaven National Laboratory, is seeking information from qualified vendors regarding the procurement of a 200kV cold-field-emission-gun (CFEG) high-resolution transmission electron microscope (HRTEM)/scanning transmission electron microscope (STEM). This advanced instrument is essential for atomic-resolution characterization and analysis of nanoscale materials, requiring specific capabilities such as high-resolution imaging, efficient detectors, and various operational modes. Interested parties are invited to submit their capabilities and responses to the attached RFI document by 3:00 PM Eastern Time on January 6, 2026, with submissions directed to Lisa Gonzales at lgonzales@bnl.gov. This RFI is for information and planning purposes only and does not constitute a solicitation for proposals.
