Abstract

The US standards Laboratory of the National Institute of Standards and Technology (NIST), has been involved in the generation and dissemination of time and frequency products within the international timing community for decades. Within the last 5 years, the completion of new laboratories and the maturity of cold atom clock technology has stimulated a series of activities that will culminate in a newly designed time scale, new possibilities for time transfer links and the creation of a stable infrastructure for comparison of optical clocks along with their use to inform the rate of the time scale itself.

This presentation gives an overview of the present state of this evolution along with a look at the near future.

 

Biography

Stefania Römisch is originally from Torino, Italy. She received her PhD in Electronic Instrumentation in 1998, from Politecnico di Torino, Italy.  She joined the National Institute of Standards and Technology (NIST) as a Guest in 1998 in Boulder, CO, and then moved to the Department of Electrical and Computer Engineering of University of Colorado also in Boulder, CO. Stefania then started her own consulting firm, Spectral Research LLC, where she developed various microwave amplifiers, synthesizers and oscillators for customers ranging from the US Government to private industries.  Finally, she joined the Time and Frequency Division of NIST in Boulder, CO.

She now leads the Atomic Standards Group at NIST whose activities include the generation of UTC(NIST), and the use of GPS and TWSTFT to contribute to Universal Coordinated Time. Her research interests span from time scale generation to the calibration of time transfer links and the application of time synchronization to fundamental physics experiments.
