The Department of Commerce, National Institute of Standards and Technology (NIST), is seeking a 100% small business set-aside for the procurement of three high-precision rotation stages to upgrade the Cold Neutron Imaging Instrument’s Phase Grating Roll Alignment System. Each stage must achieve a resolution better than 0.00005 degrees, support a 100g to 150g grating mass, maintain a total system mass under 1 kg, and enable full 360-degree rotation with zero backlash while incorporating powered-off position holding to retain alignment during power loss. The stages must include a clear aperture to permit unattenuated neutron beam passage and be paired with 10-meter-long cabling, motion sensors capable of sub-0.00001-degree angular resolution, motion control hardware, and an SDK-based C/C++/C# or .NET software suite for system control. The system must be delivered in its final, fully functional form by December 31, 2026, with no prototypes, refurbished units, or demonstration models accepted. Proposals must be submitted as a firm-fixed-price quotation via email to [email hidden] by June 23, 2026, structured into three volumes: technical capability documentation with explicit citations to requirements, a separate price quote per CLIN, and completed compliance documentation for all applicable clauses. Compliance with FAR provisions including Buy American, DEI nondiscrimination, combating trafficking in persons, and sustainable procurement is mandatory, and all vendors must maintain an active SAM.gov registration. The award will go to the lowest-priced technically acceptable offeror, with acceptance to occur at NIST’s Gaithersburg, Maryland facility after performance validation under operational conditions. Payment is issued 100% upon acceptance, following submission of an invoice to [email hidden] containing full CLIN and UEI details, and title transfers to NIST upon formal acceptance.

Full Description

Show more

The NIST neutron imaging team, in the Radiation Physics Division of the Physical Measurement Laboratory, is developing a far-field grating neutron interferometer to measure the projection of the pair correlation function, G(Z), of a sample of interest.  This interferometer geometry requires precision alignment of 3 gratings about the roll direction of the neutron beam.  Since G(Z) is a vector quantity, aligned perpendicular to the grating direction, the grating alignment stages need to be able to rotate a full 360°, with high resolution.  The gratings are lines etched into silicon wafers, where the period of the lines is of order 1 micrometer and the wafers are 100 mm in diameter.  The mass of a grating, including a holder is of order 100 g.  The interferometer pattern is measured by translating one of the gratings, so that that mass of the alignment system must be kept to as low as achievable.  For control hardware, the separation of two of the gratings along the beam ranges from 1 mm to 300 mm.  The third grating is separated by up to 5 m. The overall grating alignment system requires translating the gratings in the vertical direction, requiring that the grating roll stages (which much also translate) be less than 1 kg in mass.


This procurement is to obtain quantity three high precision rotation stages (resolution better than 0.00005 degrees) with a clear aperture to allow the beam to pass unattenuated and required cabling, control hardware, and control software.

Building 215 Clean Room HEPA Filter Replacement
Solicitation # RFI-195000-26-00181
The National Institute of Standards and Technology is conducting market research through a Request for Information for the Building 215 Advanced Measurement Laboratory cleanroom repair and HEPA filter replacement project in Gaithersburg, Maryland. This initiative follows a previous solicitation that failed to produce an acceptable offer, prompting NIST to reassess its acquisition strategy and seek industry feedback on constructability, cost, and schedule feasibility. The project scope involves the modernization of an 1,800 square meter facility, including the replacement of approximately 1,200 HEPA filters, 70 VAV terminal units, and 54 airflow monitoring devices, as well as the installation of 32 exhaust air control valves and associated ductwork repairs, testing, and recertification. A critical component of the project is the proposed phasing plan, which aims to minimize research disruptions by utilizing 19 construction phases, including 18 critical cleanroom outage phases. Each critical outage is currently envisioned as a nine-day window starting Friday evening and requiring 24/7 operations to achieve ready-for-re-occupancy by the following Monday morning. NIST is specifically requesting rough-order-of-magnitude cost estimates and industry input on whether this aggressive outage schedule is realistic or if it creates prohibitive risks and costs. Responses, including company experience and recommendations for improving competition and project execution, are due by October 14, 2026.
