ESA Welcomes Arrival Of Pharao
2014-07-29 03:14:46

ESA ESA has welcomed the arrival of Pharao, an important part of ESA’s atomic clock experiment that will be attached to the International Space Station in 2016. Delivered by France’s CNES space agency, Pharao is accurate to a second in 300 million years, which will allow scientists to test fundamental theories proposed by Albert Einstein with a precision that is impossible in laboratories on Earth. Time is linked to gravity and, for example, passes faster at the top of Mount...

National Institute of Standards and Technology (NIST) Researchers from the National Institute of Standards and Technology (NIST) and California Institute of Technology (Caltech) have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, or a microcomb. The microcomb clock, featured on the cover of the inaugural issue of the new journal Optica, is the first demonstration of all-optical control of the microcomb, and its accurate conversion of optical...

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...

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...

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...
