US made the world's most accurate atomic clock set a new record

The world's most accurate atomic clock will only deviate a second for 15 billion years.

The most accurate atomic clock in the world

According to experts at the National Institute of Standards and Technology (NIST), with this change, the strontium atomic clock is the most accurate and stable ever produced . In the journal Nature Communications, atomic clocks are accurately depicted three times over last year, when the previous world record was set.

The Times says the watch is made up of several thousand statorium atoms , held in 30x30 microns in an optical network formed by intense laser light. Its stability is improved to 50%.

This device can measure small changes over time and gravity at different heights. It can also be used in geodetic studies, when using a grid of clocks as gravity sensors to perform Earth measurements.

To improve the flaws in the ambient heat, the researchers inserted two platinum resistance thermometers into the vacuum chamber and formed a radiation shield around the atomic chamber. As a result, the meter can operate at room temperature instead of the cold environment.
