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...

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...

Redefining Time With Innovative Optical Lattice Clock
2013-07-10 12:56:58

Michael Harper for redOrbit.com - Your Universe Online Atomic clocks are the standard in time, hailed as the most accurate and often used to keep other clocks on time. Now, a new kind of clock aims not only to replace atomic clocks as the most accurate, but to redefine the second as a measurement of time as well. The new device, called an optical lattice clock (OLC) is, theoretically, three times more accurate than current atomic clocks. In computer models, these clocks lost only one...
