About this opportunity
SLAC National Accelerator Laboratory, operated by Stanford University for the Department of Energy, is procuring high quality High Pressure High Temperature (HPHT) diamond crystals for X-ray optics applications. The laboratory requires 2 pieces of diamond crystals with specific dimensional and quality requirements: crystals must be larger than 3mm x 4mm x 0.5mm with (1 1 0) crystal surfaces, grown using HPHT methods, and exhibit distortion and strains of less than 15 microradians in a 1mm x 1mm area. The procurement specifies a requirement for U.S. domestic end item sources and mandates that offerors be registered with the System for Award Management (SAM). The award will be made using the Lowest Price Technically Acceptable (LPTA) evaluation method, with technical evaluation focusing on crystal growth method, size specifications, crystal surface orientation, and distortion tolerances. The original solicitation was posted on October 8, 2025, with a response deadline of October 23, 2025, and Amendment 01 clarified that mono-sectorial diamond is preferred, though multi-sectorial diamond is acceptable if the largest sector comprises more than 50% of the surface.
This solicitation does not utilize any set-aside designations and is open to all qualified vendors meeting the technical and registration requirements. No incumbent contractors or current service providers are identified in the procurement documents. The solicitation does not specify award values or budget ranges, focusing instead on technical compliance and lowest price evaluation criteria. The contract requires delivery of exactly 2 pieces of specialized diamond crystals to SLAC National Accelerator Laboratory located at 2575 Sand Hill Road, Menlo Park, California 94025. Performance will be governed by SLAC's Terms and Conditions for Fixed Price Commercial Supplies and Services dated August 2023, and successful vendors must complete various representations and certifications including Buy American Act compliance documentation.
