International timescales with optical clocks
Annotation in Czech
The most advanced optical atomic clocks have now reached levels of stability and accuracy that surpass the performance of the best caesium fountain primary standards. The Al+ optical clock at NIST has an estimated systematic uncertainty of 8.6 parts in 1018, and several other optical clocks have also reached uncertainties below 1 part in 1016. As a result, an optical redefinition of the SI second is being actively considered by the international metrology community. This JRP addresses the key steps thatmust be carried out before such a redefinition can take place, and will thus enable European NMIs to play an influential role in international debates on this matter.
