It might not fit on your wrist or look good hanging on the wall, but this atomic ... NIST-F1 cesium clock, the current U. S. civilian time standard, clock performance must be averaged over 400,000 sec (or about five days). The new ytterbium
This is the ion trap of the ytterbium clock at PTB. (Photo: PTB) The faster a clock ticks, the more precise it can be. Due to the fact that lightwaves vibrate faster than microwaves, optical clocks can be more precise than the caesium atomic
The new strontium clock is so precise it would neither gain ... each tick matches the duration of every other tick - is about the same as NIST's ytterbium atomic clock. Stability determines in part how long an atomic clock must run to …
Heralding a new age of terrific timekeeping ... The strontium clock’s stability—the extent to which each tick matches the duration of every other tick—is about the same as NIST’s ytterbium atomic clock, another world leader in stability …
A pair of experimental atomic clocks based on ytterbium atoms has set a new record for stability, researchers said. The clocks act like 21st century pendulums or metronomes that could swing back and forth with perfect timing for a period …
While mechanical clocks use the movement of a pendulum to keep time, atomic clocks use an electromagnetic signal of ... to obtain its best performance. But the new ytterbium clocks can achieve that same result in about one second of …
Their newest atomic ... behind this new clock have done is create an innovative design (using a different element) that minimizes these distortions more than any clock before. Their design, called an “optical lattice clock,” traps ytterbium
The more stable the clock, the better its measurement power. The new ytterbium lattice 'double clock' is the most stable clock in the world, although another NIST atomic clock, based on strontium and located at JILA, holds the world …
Scientists at the National Institute of Standards and Technology have gotten a step closer to figuring out time with a new ytterbium-based atomic clock. The new clock is so accurate that the differences in measuring one second to the …
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 ... same as NIST’s ytterbium atomic
