HOUSTON, Sept. 21 /PRNewswire/ -- Integrated Electrical Services (www.ies-co.com) (Nasdaq: IESC), a leading national provider of electrical and communications systems and services for the commercial, industrial and residential markets, announced today that it has been awarded a contract for the installation of electrical systems at the Precision Measurement Laboratory (PML) at the National Institute of Standards and Technology in Boulder, Colo. (NIST) (www.boulder.nist.gov). IES is...

Maintaining the correct time is no longer just a matter of keeping your watch wound -- especially when it comes to computers, telecommunications, and other complex systems. The clocks in these devices must stay accurate to within nanoseconds because their oscillators -- objects, like quartz crystals, which repeat the same motion over and over again -- are synchronized to agree with the clocks on board Global Positioning System (GPS) satellites. In the journal Review of Scientific Instruments,...

In an advance that sounds almost Zen, researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado at Boulder, have demonstrated a new type of pulsed laser that excels at not producing light. The new device generates sustained streams of "dark pulses""”repeated dips in light intensity"”which is the opposite of the bright bursts in a typical pulsed laser. Despite its ominous name, the dark pulse laser is...

Clocks in the Americas and the Caribbean Islands are now ticking in unison thanks to the work of the Sistema Interamericano de Metrologia (SIM), a regional metrology organization that works to promote accurate measurements throughout the Americas. Since 2005, SIM has been building a time network, designed by the U.S. National Institute of Standards and Technology (NIST), that now extends to 16 nations. The SIM Time Network allows each of these nations to continuously compare their clocks,...

JILA scientists use electric fields to control chemical reactions of ultracold molecules Physicists at JILA have demonstrated a new tool for controlling ultracold gases and ultracold chemistry: electric fields. As described in the April 29 issue of Nature,* JILA scientists discovered that applying a small electric field spurs a dramatic increase in chemical reactions in their gas of ultracold molecules. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and...

Clock keeps time to 1 second in 3.7 billion years Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world's most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom. The new aluminum clock would neither gain nor lose one second in about 3.7 billion years, according to measurements to be reported in Physical Review...

Yesterday at the Paris headquarters of the French space agency (CNES), Simonetta Di Pippo, ESA Director of Human Spaceflight, and Thierry Duquesne, CNES Director for Strategy, Programs and International Relations, signed an agreement that paves the way for the launch of a high-accuracy atomic clock to be attached to the outside of the European Columbus laboratory onboard the International Space Station (ISS). The PHARAO (Projet d'Horloge Atomique par Refroidissement d'Atomes en Orbite)...

The world's best caesium atomic clocks control Coordinated Universal Time (UTC), an atomic time scale on which the time zones used in everyday life are based. But also in navigation (GPS), astronomy, telecommunications, geodesy and physical fundamental research, accurate timing is of essential importance. Until recently, three of PTB's clocks belonged to the exclusive club of primary caesium atomic clocks. Now a fourth one, the caesium fountain clock CSF2, has joined in. This month, its data...

Joint project between PTB and its US counterpart NIST might advance simple and cost effective diagnostical methods The "magnetically best shielded room on earth" has the size of an apartment block and is located on the site of the Physikalisch-Technische Bundesanstalt (PTB), Institute Berlin. Magnetic fields such as that of the earth are kept out here as effective as nowhere else. Such ideal conditions allow to measure the tiny magnetic fields of, e.g., the human heart. This was the...
