Rocky Mountain Eagle Award Winners
On May Three physicists – Chris Oates, Jun Ye, and Andrew Ludlow of PML’s optical atomic clock team – received the Rocky Mountain Eagle Award for Scientific Project or Achievement. The annual awards, given by the Colorado Federal Executive Board, are one of the most important forms of non-monetary recognition available to federal government employees within the State of Colorado. They are intended to provide the opportunity to communicate to the public the outstanding achievements of federal employees who have dedicated their careers to public service.NIST research groups at JILA and NIST-Boulder have been pursuing next generation optical atomic clocks based upon lasers whose frequencies are locked to ultra-narrow transitions in large samples of neutral atoms held in laser traps, termed “optical lattices”. The group at JILA, led by Ye, has demonstrated unprecedented clock performance with strontium atoms; the team at NIST-Boulder, led by Ludlow and Oates, has reached new levels of atomic clock precision using ytterbium atoms. Recent results by these groups have considerably advanced atomic clock performance and could one day lead to a new definition of the second. The award winners share “family” roots: They all performed their Ph. D. thesis experiments in the same room at the University of Colorado (Ye and Oates under the guidance of NIST Nobel Laureate John Hall; and Ludlow, some years later, under the guidance of Ye).
Jay Hendricks of the Sensor Science Division’s Thermodynamic Metrology Group has been elected chair of the Vacuum Science and Technology Division (VSTD) within the International Union for Vacuum Science, Technique and Applications (IUVSTA).

OWM Al Sur
Carol Hockert and Georgia Harris of the Office of Weights and Measures (OWM) presented a two-day training workshop on “Fundamentals of Metrology and Testing” in Medellin, Colombia on May 6 - 7. The workshop was originally planned for 20 participants. A month prior to the session, Hockert and Harris were asked if they could provide the course to 30, with a waiting list of 20. On arrival, they found that there would be 80 participants in the course, which included simultaneous translations. Course content was extracted from OWM’s “Fundamentals of Metrology” course and several of the OWM webinars, and instruction focused on ensuring and assessing metrological traceability in measurement results. Participants brought their own calibration certificates and found numerous problems.
After the workshop, Hockert and Harris presented at the “First International Congress for Legal, Biomedical, and Industrial Metrology” on May 8 - 9 for about 350 people on the following five topics: The U.S. Approach to Legal Metrology, Quality Tools for Metrology, Mass and Balances for Legal Metrology, Volume Calibrations for Legal Metrology, and Assessments of Traceability and Proficiency.
Training and presentations were all provided by request and subsidized by the Metrology Congress.

U.S. Patent number 8,543,356 – Low cost multi-channel data acquisition system, invented by Alan Migdall and Sergey Polyakov of the Quantum Optics Group, and Sae Woo Nam of the Quantum Electronics and Photonics Group – has been issued and assigned to NIST.
From the patent abstract: “Embodiments of the present invention provide an inexpensive and fast pulse characterization platform capable of real time operation, suitable for acquisition of single-photon data. Embodiments of the present invention include both a digital multi-channel data acquisition instrument and an analog pulse acquisition instrument suitable for a wide range of applications in physics laboratories. An FPGA performs multi-channel acquisition in real time, time stamps single events, and determines if the events fit a predetermined signature, which causes the events to be categorized as a coincidence. The indications of coincidences are then communicated to a host computer for further processing as desired.”
