Some scientific highlights include: The world-leading accuracy of the aluminum ion clocks in the Ion Storage Group and the world leading precision of the ytterbium (Yb) lattice clocks in the Neutral Atom Optical Clocks Group as well as the development of a portable Yb optical lattice clock as a new tool for high-precision optical clock comparisons.

The Phase Noise Metrology Group provides valuable microwave phase noise calibration and measurement services to industry and the Department of Defense. The division is also world-leading in the development of cutting-edge time- and frequency-related technologies with higher technology readiness levels that are industry and application oriented and are also relevant to other scientific disciplines: The Atomic Devices and Instrumentation Group vigorously innovates in the area of compact, low-power quantum sensors and clocks and leads research efforts in the $10 million/year NIST on a Chip program.

There are important opportunities for expanding the phase noise characterization services and capabilities performed by the Phase Noise Metrology groups to higher frequencies (terahertz) and optical phase noise measurements in conjunction with the Precision Photonic Synthesis Group, to keep pace with the development of new and emerging communications and metrology technologies.

, are subject to construction noise, have experienced flooding, have issues with pests, and can be located very close to actual construction, causing disturbances to workflows or incurring safety issues. It has also been noted by key staff that once the renovations have been completed, all available laboratory and office space will likely be completely filled, with no room for growth or innovation (this was referenced by one NIST staff scientist as "The renovations will be appropriate for 2010 needs, not 2030 needs")

Naval Observatory, Fort Collins, and the NIST Gaithersburg campus. Similarly, as noted in Recommendation 6-2, the Time Realization and Distribution Group needs more funding and personnel dedicated to its time services, commensurate with the crucial role these serve for the country.

to notify industry. Monitoring traffic to these website areas and subscriber lists would also add to the numerous ways the division already employs to measure stakeholder impact, such as tallying 100 billion network time protocol requests per day, more than 60 subscribers to Time and Frequency Measurement and Analysis Services, and the division's numerous publications, citations, publication journals, collaborators, patents, licenses, and disclosures.
