Atomic Alarm Clocks
There are many different devices that have been invented that all keep the time. Many of these new pieces of technology not only tell the time but they also have other useful functions. Some allow us, the public, to keep track of our daily activities. Some are utilised for lab purposes. One such clock designed for this purpose in the atomic alarm clock.
At present atomic alarm clocks are found only in a few different forms. These include caesium atomic beam, rubidium gas cell and the hydrogen maser. Of this small list of clocks you will find that the hydrogen maser clock is considered the most stable.
The rubidium gas cell is thought of as being the least expensive of the atomic alarm clocks. It is also known to have good short term stability and it is compact in size. The caesium beam on the other hand is known for it high accuracy. Long term stability can be achieved with all these atomic alarm clocks.
Due to the fact that the caesium beam is highly accurate it has become the international definition of the second. This means that in situations where vary fine accuracy is required in timekeeping you will find a caesium beam being employed.
Alongside the atomic alarm clock you will find others that are similar. These clocks can be known as rubidium masers, thallium atomic beam and ammonia masers. If you look into the history of the manufacturing of these clocks you will see that the very first atomic clock was created in 1949.
This atomic alarm clock was designed and constructed at the National Bureau of Standards. Today you will find that these atomic alarm clocks are being used as quartz oscillators. For these clocks to be used in this way their high accuracy is not required so therefore it may be a good idea to choose from one of the above well known atomic alarm clocks.
These other alarm clocks are also used in the application of keeping track of the international time scale and in keeping time in the Global Positioning System. Other uses for this type of clock are that of radio astronomy, satellite, navigation systems, digital communication systems and electronic communications.
As you will see when browsing through atomic alarm clocks these clocks are not regularly used by the public but they do have an important role to play in our lives. When you see the various applications that these atomic alarm clocks are used for, you will begin to understand the many uses that time keeping devices, of any sort, can be used for.
