New clock won’t lose a second in 300m yrs
- A new atomic clock NIST-F2 has been developed which would neither gain nor lose one second in about 300 million years, making it 3 times more accurate than its predecessor.
- It was launched by USA’s National Institute of Standards and Technology (NIST), to serve as a new US civilian time & frequency standard along with existing NIST-F1 standard.
- NIST-F1 & F2 use a fountain of Cesium atoms to determine the exact length of a second.
- The performance of NIFT-F2 has been reported to the International Bureau of Weights and Measures (BIPM), located near Paris, France.
