New Method Could Make Sub-wavelength Images At Radio Frequencies
2014-06-18 03:12:08

By Laura Ost, National Institute of Standards and Technology (NIST) Imaging and mapping of electric fields at radio frequencies (RF) currently requires the use of metallic structures such as dipoles, probes and reference antennas. To make such measurements efficiently, the size of these structures needs to be on the order of the wavelength of the RF fields to be mapped. This poses practical limitations on the smallest features that can be measured. New theoretical and experimental work...

Karlsruhe Institute of Technology Researchers Exploit Optical Frequency Comb Sources on a Silicon Chip for Data Transmission in the Terabit Range Miniaturized optical frequency comb sources allow for transmission of data streams of several terabits per second over hundreds of kilometers – this has now been demonstrated by researchers of Karlsruhe Institute of Technology (KIT) and the Swiss École Polytechnique Fédérale de Lausanne (EPFL) in a experiment presented in the journal...

New U.S. Time Standard Launched By NIST
2014-04-04 13:21:23

[ Watch The Video: NIST-F2 Atomic Clock Sets The Time Standard ] NIST The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has officially launched a new atomic clock, called NIST-F2, to serve as a new US civilian time and frequency standard, along with the current NIST-F1 standard. NIST-F2 would neither gain nor lose one second in about 300 million years, making it about three times as accurate as NIST-F1, which has served as the standard...

Integrating the atomic clock inside the MS2720T provides field engineers...

JILA Strontium Atomic Clock Unveiled And Sets New Records In Precision, Stability
2014-01-23 09:53:25

National Institute of Standards and Technology (NIST) Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability-- key metrics for the performance of a clock. The clock is in a laboratory at JILA, a joint institute of NIST and the University of Colorado Boulder. Described in a new paper in...

New Compact Atomic Clock Design Uses Cold Atoms To Boost Precision
2013-11-06 12:03:09

National Institute of Standards and Technology (NIST) Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability. Described in a new paper, the heart of the prototype clock (the vacuum chamber containing the atoms) is about the size of a coffee mug, 150 cubic centimeters, set in a small table of lasers and...

Connecting Clocks To Measure Height

Physikalisch-Technische Bundesanstalt (PTB) Researchers from Garching and Braunschweig transport frequencies with high precision over almost 2000 km - important, among other things, for geodesy How far above sea level is a place located? And where exactly is "sea level"? It is one objective of the geodesists to answer these questions with 1 cm accuracy. Conventional measurement procedures or GPS technologies via satellites, however, reach their limits here. Now optical atomic clocks...

Science Community now has entire system available to help drive applications into BEC and Ultracold Atoms. Boulder, CO (PRWEB) September 05, 2013 Notoriously difficult, expensive and time consuming to set up, experiments to create Bose-Einstein Condensates (atoms cooled to temperatures very close to Absolute Zero) have become vastly easier yet much smaller in size. When Eric Cornell and Carl Wieman first demonstrated the existence of as Bose-Einstein Condensate (BEC), a form of ultracold...

New Stability Record Set By NIST Ytterbium Atomic Clocks
2013-08-22 14:45:09

National Institute of Standards and Technology (NIST) A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect timing for a period comparable to the age of the universe. NIST physicists report in the Aug. 22 issue of Science Express that the ytterbium clocks' tick is more stable than...

Word of the Day
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
