Across SSD's groups and programs, the division is responsible for developing, maintaining, and disseminating national measurement standards for these physical quantities; performing measurement comparisons internationally to support U.S. competitiveness in the global marketplace; performing research for new measurement technologies, methods, and national needs; and providing measurement services, including the calibration of practical standards and measurement instruments.

The published results of these key comparisons confirm that NIST staff demonstrably are leaders in many measurement disciplines, achieving some of the lowest measurement uncertainties in the world. In terms of impact on advanced manufacturing, it is important to note that nearly all large-scale metrology tools are specified and tested according to standards developed under SSD staff leadership.

. The SSD used this capability for industry collaborations in the areas of testing EUV optics lifetimes and identifying optics degradation methods; photoresist characterization (e.g., all advanced semiconductor materials lithography)

to provide calibration of the approximately $5 × 1012 per year sale of petroleum products. API documentary standards require recalibration of test measures every 5 years, with SSD involvement in the recalibration due to its impartiality, measurement consistency and quality protocols, and the SSD's continuing research to improve liquid volume measurements.

An impressive recent accomplishment is the development of the telescope for lunar spectral irradiance calibration, which is suitable for deployment on a high-altitude aircraft and was successfully deployed in a demonstration flight campaign. This facility realized a considerable reduction of lunar spectral irradiance measurement uncertainty, helping to improve climate measurements from satellites.

The division leads global documentary standards activities for general measurement competency and specific industrial sectors, in support of the NIST, PML, and SSD missions. ADEQUACY OF RESOURCES The aging infrastructure has negatively affected performance of mission-critical activities in the form of facilities downtime, burdening technical personnel (because they have to spend time reacting to and compensating for deficient environmental conditions and not in performing measurements)

From page 34... ...
The division is active in participating in or leading interlaboratory measurement comparisons, which generate cooperative agreements with industry, government, and universities, as well as interagency agreements. SSD staff participate in over 25 standards developing organizations and consultative committees that produce documentary standards, leading approximately 58 of these committees, with 8 documentary standards and draft documentary standards in dimensional metrology published since 2017.

RECOMMENDATION: The Sensor Science Division should reexamine the design and implementation of the NIST Storefront based on conversations with division staff and customers. The division should also perform an assessment of which measurements, calibrations, and standard reference materials are no longer available but are still listed on the Storefront as being offered.
