Toward an Optical Atomic Clock: Physicists Develop Atomic Frequency Standard for One of World’s Most Precise Clocks

Polish physicists accept been aiming to body an optical diminutive clock, an acutely absolute accessory with an accurateness of one additional in a few dozen billion years, back 2008. The aftermost of the three key apparatus of the clock: an diminutive abundance accepted based on algid strontium atoms has aloof been developed at the Department of Photonics, Institute of Physics, Jagiellonian University. The alarm itself will be accumulated already this year.
The architecture of a Polish optical diminutive clock, a accessory of attention rarely akin in the world, will anon access its final phase. A accumulation led by Prof. Wojciech Gawlik at the Department of Photonics, Institute of Physics, Jagiellonian University has aloof complete the aftermost of the key apparatus appropriate for the architecture of the clock: an diminutive accepted based on algid strontium atoms. Afterwards the cessation of a alternation of tests, the accessory will be transported to the National Laboratory for Atomic, Molecular and Optical Physics (KL FAMO) in Toruń, area physicists will amalgamate it with the two actual components: an optical adjust developed by a accumulation led by Prof. Czesław Radzewicz from the University of Warsaw (UW) and an ultra-precise laser congenital beneath the administration of Roman Ciuryłło, PhD, at the Nicolaus Copernicus University (UMK).
Precise time abstracts are of key accent to the able activity of our civilization. Without them, avant-garde telecommunication and aeronautics systems, decidedly accessory systems, would cease to function. Ultra-precise clocks are additionally basal for analysis on the axiological backdrop of reality, amid others, for investigating whether the ethics of concrete constants are absolutely connected and investigating the admeasurement to which the accepted approach of relativity provides an authentic description of the Universe.
The Polish optical diminutive alarm architecture project, financed alone by the Ministry of Science and College Education, was started two years ago and is conducted by groups of physicists from all over Poland, currently accommodating aural the framework of KL FAMO which is a allotment of the National Laboratory for Breakthrough Technologies. The abstract attention of time abstracts of the alarm beneath architecture will be two orders of consequence greater than that of the best absolute cesium clocks, which are currently used, amid others, to ascertain the accepted second. “The Polish alarm will accept an accurateness of one additional in a few dozen billion years, which is a aeon several times best than that which delayed from the Big Bang. Such absolute timekeeping accessories can nowadays be begin alone in a scattering of analysis centres in the world,” says Prof. Wojciech Gawlik, arch of the aggregation of physicists from Cracow.
All clocks accomplish use of a assertive abundance standard, a alternate concrete phenomenon. In the case of a wristwatch, the accepted is a quartz resonator with an aquiver quartz crystal. Commonly acclimated diminutive clocks accomplish use of an cyberbanking alteration amid activity levels in cesium atoms. The physicists from Cracow, on the added hand, accept complete a accepted based on strontium atoms, in which cyberbanking transitions amid diminutive activity levels crave assimilation and discharge of electromagnetic radiation of a abundant college abundance than in cesium. The abundance lies in the optical ambit (hence the adjective “optical” in the name of the clock). Confined in a laser trap, strontium atoms are abandoned from the ambience and cooled with a laser to an acutely low temperature of the adjustment of microkelvins. Beneath these conditions, the anticipation of diminutive collisions is low, which abundantly reduces the achievability of disturbance. The new accepted is currently ability the aboriginal tests.
The abundance accepted based on strontium atoms is one of the apparatus of the optical diminutive clock. It will be acclimated to balance the abundance of the ultra-precise laser congenital in Toruń. It is absolutely the accordance of the electric acreage of a ablaze axle emitted by the laser that will be counted as elementary units of time, alternating with abundant precision. Yet the laser operates with such a aerial abundance that counting the alone oscillations is above the capabilities of cyberbanking systems. What is bare is a accessory which acts as a asperous gear. The accessory in catechism is a abundance adjust — a set of abundant ablaze after-effects of narrow, centermost frequencies. The comb, generated by a laser abounding ultra-short ablaze pulses, allows for a accompanying and error-free alteration of diminutive accepted oscillations into radio beachcomber abundance ambit — radio after-effects can be electronically counted. The abundance adjust has already been operated by scientists from the Ultrafast Phenomena Laboratory of the Institute of Experimental Physics, University of Warsaw and preliminarily accumulated with a bartering advertence laser of a counterbalanced abundance of light. Works are currently underway to amalgamate it with the ultra-precise laser congenital at the National Laboratory FAMO in Toruń.
“Our diminutive accepted based on strontium atoms is the third, final allotment of the puzzle. In several months’ time, afterwards the tests and afterwards alteration it to Toruń, we will be able to alpha putting the alarm together,” observes Prof. Gawlik.
The National Laboratory for Breakthrough Technologies (nltk.fuw.edu.pl) is a bunch of arch Polish accurate institutions administering analysis in the acreage of breakthrough technologies, including breakthrough computing, breakthrough engineering and accompanying fields. The NLTK consists of: the University of Warsaw, the Wrocław University of Technology, the Institute of Physics of the Polish Academy of Sciences, the Nicolaus Copernicus University in Toruń, the Jagiellonian University, the University of Gdańsk, the University of Łódź, and the Center for Abstract Physics of the Polish Academy of Sciences. A activity of the aforementioned name is agitated out in bristles of the eight institutions of the NLTK consortium. The aim of the activity is to actualize and accouter the affiliate accurate institutions with accessories all-important for administering world-class collective accurate analysis as able-bodied as analysis and development.

Hot Plasma Explosions Inflate Saturn’s Magnetic Field

This is an artist’s abstraction of the Saturnian claret area based on abstracts from Cassini magnetospheric imaging instrument.

A new assay based on abstracts from NASA’s Cassini aircraft finds a causal articulation amid mysterious, alternate signals from Saturn’s alluring acreage and explosions of hot ionized gas, accepted as plasma, about the planet.
Scientists accept activate that astronomic clouds of claret periodically blossom about Saturn and move about the planet like an asymmetric amount of laundry on circuit cycle. The movement of this hot claret produces a repeating signature ‘thump’ in abstracts of Saturn’s alternating alluring ambiance and helps to allegorize why scientists accept had such a difficult time barometer the breadth of a day on Saturn.
‘This is a advance that may point us to the agent of the mysteriously alteration periodicities that billow the accurate circling aeon of Saturn,’ said Pontus Brandt, the advance columnist on the cardboard and a Cassini aggregation scientist based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. ‘The big catechism now is why these explosions action periodically.’
The abstracts appearance how claret injections, electrical currents and Saturn’s alluring acreage — phenomena that are airy to the animal eye — are ally in an intricate choreography. Alternate claret explosions anatomy islands of burden that circle about Saturn. The islands of burden ‘inflate’ the alluring field.
A new action assuming the affiliated behavior is accessible at http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov .
The decision shows how airy hot claret in Saturn’s magnetosphere – the alluring balloon about the planet — explodes and distorts alluring acreage curve in acknowledgment to the pressure. Saturn’s magnetosphere is not a absolute balloon because it is absolute aback by the force of the solar wind, which contains answerable particles alive off the sun.
The force of the solar wind stretches the alluring acreage of the ancillary of Saturn adverse abroad from the sun into a alleged magnetotail. The collapse of the magnetotail appears to bang off a action that causes the hot claret bursts, which in about-face aerate the alluring acreage in the close magnetosphere.
Scientists are still investigating what causes Saturn’s magnetotail to collapse, but there are able break that cold, close claret originally from Saturn’s moon Enceladus rotates with Saturn. Centrifugal armament amplitude the alluring acreage until allotment of the appendage snaps back.
The snapping aback heats claret about Saturn and the acrimonious claret becomes trapped in the alluring field. It rotates about the planet in islands at the acceleration of about 100 kilometers per additional (200,000 mph). In the aforementioned way that aerial and low burden systems on Earth account winds, the aerial pressures of amplitude account electrical currents. Currents account alluring acreage distortions.
A radio arresting accepted as Saturn Kilometric Radiation, which scientists accept acclimated to appraisal the breadth of a day on Saturn, is carefully affiliated to the behavior of Saturn’s alluring field. Because Saturn has no apparent or anchored point to alarm its circling rate, scientists accepted the circling amount from timing the peaks in this blazon of radio emission, which is affected to billow with anniversary circling of a planet. This adjustment has formed for Jupiter, but the Saturn signals accept varied. Abstracts from the aboriginal 1980s taken by NASA’s Voyager spacecraft, abstracts acquired in 2000 by the ESA/NASA Ulysses mission, and Cassini abstracts from about 2003 to the present alter by a small, but cogent degree. As a result, scientists are not abiding how continued a Saturn day is.
‘What’s important about this new assignment is that scientists are alpha to call the global, causal relationships amid some of the complex, airy armament that appearance the Saturn environment,’ said Marcia Burton, the Cassini fields and particles analysis scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. ‘The new after-effects still don’t accord us the breadth of a Saturn day, but they do accord us important clues to activate addition it out. The Saturn day length, or Saturn’s circling rate, is important for free axiological backdrop of Saturn, like the anatomy of its autogenous and the acceleration of its winds.’
Plasma is airy to the animal eye. But the ion and aloof camera on Cassini’s magnetospheric imaging apparatus provides a three-dimensional appearance by audition active aloof atoms emitted from the claret clouds about Saturn. Active aloof atoms anatomy back cold, aloof gas collides with electrically-charged particles in a billow of plasma. The consistent particles are neutrally charged, so they are able to escape alluring fields and zoom off into space. The discharge of these particles generally occurs in the alluring fields surrounding planets.
By stringing calm images acquired every bisected hour, scientists produced movies of claret as it drifted about the planet. Scientists acclimated these images to reconstruct the 3-D burden produced by the claret clouds, and supplemented those after-effects with claret pressures acquired from the Cassini claret spectrometer. Once scientists accepted the burden and its evolution, they could account the associated alluring acreage perturbations forth the Cassini flight path. The affected acreage perturbation akin the empiric alluring acreage ‘thumps’ perfectly, acknowledging the antecedent of the acreage oscillations.
‘We all apperceive that alteration circling periods accept been empiric at pulsars, millions of ablaze years from our solar system, and now we acquisition that a agnate abnormality is empiric appropriate actuality at Saturn,’ said Tom Krimigis, arch investigator of the magnetospheric imaging instrument, additionally based at the Applied Physics Laboratory and the Academy of Athens, Greece. ‘With instruments appropriate at the atom area it’s happening, we can acquaint that claret flows and circuitous accepted systems can affectation the absolute circling aeon of the axial body. That’s how observations in our solar arrangement advice us accept what is apparent in abroad astrophysical objects.’
The Cassini-Huygens mission is a accommodating activity of NASA, the European Amplitude Agency and the Italian Amplitude Agency. NASA’s Jet Propulsion Laboratory, a analysis of the California Institute of Technology in Pasadena, Calif. manages the mission for NASA’s Science Mission Directorate, Washington, D.C. The alluring imaging apparatus aggregation is based at the Johns Hopkins University Applied Physics Laboratory, Laurel, Md.
