Large Atomic Wall Clock With Cesium Fountain

When it comes to buying large atomic wall clocks, you may have a hard time deciding which is best. There are many options out there, but what’s the most accurate and durable clock? Read on to learn about the NIST-F1 and TAI clocks, and the Cesium fountain. Listed below are some important factors to consider. These clocks provide a high level of accuracy, so they can be used in any room in the house.


The NIST-F1 large atomic wall-clock features a fountain-like movement that measures time interval and frequency. The clock works by cooling a gas of cesium atoms to near-absolute zero before gently pushing the atoms into a ball. Because these atoms are so heavy, the entire process takes about a minute. When you’re ready to buy an atomic wall-clock, the best way to start your search is to read its specifications.

The NIST-F1 is a giant atomic wall clock that measures time using the vibrations of the atoms in the radioactive elements cesium and uranium. As the United States’ standard atomic clock, it would not gain or lose a second over a 30 million-year period. As a result, atomic clocks are essential for many modern systems that rely on precision. For instance, the GPS navigation system and the internet are dependent on the Coordinated Universal Time system.

While pendulum and quartz crystal clocks are more accurate than atomic clocks, they are not as reliable. Their hands spin at a much higher rate when a signal is received. Furthermore, atomic clocks are radio-controlled and are more accurate than other types of clocks. Atomic clocks are the most accurate and stable timekeeping devices on the market. They keep the time better than any other clock – better than the Earth’s rotation and the movements of the stars.


The Marathon large atomic wall clock comes with a wood-effect frame and big numbers. The split-second accuracy of the Marathon large atomic wall clock is impressive. It also displays the date, day, month, and indoor room temperature. It has a built-in kickstand for standing it up. This clock gets its time from the atomic clock that is received in North America via radio signal. It’s also water-resistant.

The Marathon Jumbo Atomic Wall Clock with Table Stand is a sleek and modern design that uses radio frequencies from the Colorado Atomic Clock to show the time.

TAI is an abbreviation for the International Atomic Time (TAI). The underlying physics behind the timekeeping system relies on six standard cesium clocks that are continually operated or periodically re-calibrated. The day-to-day TAI time scale is comprised of about 175 commercial cesium clocks located at about 30 observatories and laboratories. The TAI second accurately reproduces the SI second to one part in a billion years. In some cases, the TAI time-scale is so accurate that it has an uptime of over 90 percent.

This atomic wall clock features a 4″ tall LCD time display with an integrated stand. The large clock features a wireless outdoor sensor for easy placement in a 100-feet range of another unit. No wires are necessary. This makes it easy to place the clock anywhere in your home or office without the worry of wires tangled up. Its rounded, minimalist design will make it a stylish addition to any room.

The main contributions to R are due to variations in Earth’s speed and distance from the Sun, which cause periodic relativistic deviations in TAI. The distance between the pulsar and Earth is another factor that affects the TAI time scale. This effect has been proven by observations of pulsar PSR 1937+21. Its rotational speed is the highest of any pulsar. The period of one pulse is 1.55 microseconds, and it changes by 3.3 milliseconds in a year.

Cesium fountain

A Large Atomic Wall Clock with Cesium Fountain is an impressive piece of wall decor. The mechanism behind this timepiece is quite simple. A ball of 10 million cesium atoms is released into a cylinder that has four layers of magnetic shielding. This maser is calibrated to an exact frequency, and forces the outer electrons to transition from one state to another. The ball of cesium then falls back to its original position, where it is measured.

The Cesium atoms in an atomic clock cause the clock to ‘bounce’ off of surfaces. As a result, the cesium atoms constantly bump against each other, changing their spin rates. This is one of the reasons why atomic clocks cannot guarantee nanosecond accuracy. But researchers have proposed a solution to minimize the number of collisions by replacing the wide cesium atoms with smaller rubidium atoms. This solution reduces the error by up to 30 percent.

The NIST-F1 atomic clock is used as the primary time standard for the United States. The clock was developed at the NIST laboratory in Boulder, Colorado and contributes to the international group of atomic clocks that define Coordinated Universal Time, or official world time. The NIST-F1 is among the most accurate clocks in the world. This makes Coordinated Universal Time (UTC) more accurate than it has ever been.

TAI time-scale

Until 1977, TAI time-scales were not corrected for gravitational redshift, but were rather based on a weighted average of the rates of different atomic clocks. Because the Earth’s rotation changes in seasonality, the TAI clocks were also slightly off. The mid-1980s wobble was caused by environmental changes in some locations, but the CCTF working group deemed that the TAI time-scale should be corrected for thermal radiation. In 1997, the CIPM affirmed that corrections should be made, and over three years the TAI time-scale was leveled. The final levelling of the TAI curve has been achieved with cesium atoms at 0 Kelvin.

In approximately four thousand to five thousand years, TI will be ahead of UT1 by a full day. Because of this difference, the atomic time-scale cannot be used to calculate the calendar date, which is also a problem. Its value is approaching 1.5 billion. Furthermore, it cannot be used to calculate the dates of the seven-day week. Therefore, it is important to have a clock that accurately tells the time for the same day in different time zones.

While TAI is considered an atomic time scale, the accuracy of this time scale is still not quite accurate. It still requires some calibration, but there are no official standards. Fortunately, many atomic clocks are now calibrated using a TAI time-scale, which can be a great option for your home. In the meantime, atomic clocks can be a decorative piece for any home.

At-home atomic clocks

Large at-home atomic clocks are a great way to keep track of time. These clocks come in a variety of styles, and some have additional features like a perpetual calendar and a day of the week. Many of these clocks can be placed anywhere, including on a desk or on a wall. They are extremely easy to read and set up, making them an ideal choice for seniors.

Currently, atomic clocks can only be found in research facilities, but new technology may bring them to homes and businesses everywhere. A new fibre optic technique developed by scientists at the University of Western Australia and the University of Adelaide could help us measure time accurately at home. The technology is not much different from the way National Broadband Network modems work. A paper about the research was published this week in the journal Optics Letters. Other contributors to the paper include the Australian National University and the National Measurement Institute.

To operate atomic clocks, a signal from a time signal station is transmitted. Signal reception depends on the time signal’s strength and the weather conditions, such as high-pressure or low-lying fog. Also, distance affects the accuracy of the clock. In far-off regions, the radio signal might take too long to reach its destination, resulting in a mismatch in time. To prevent these issues, consider using a home automation gateway.
