Global Collaboration Achieves Unprecedented Precision in Redefining the Second
Originally Published 6 months ago — by National Institute of Standards and Technology (.gov)
Researchers at NIST have developed the most accurate atomic clock based on a trapped aluminum ion, achieving 19 decimal places of accuracy and surpassing previous records by 41%. The clock's enhanced stability and precision are due to improvements in the ion trap design, vacuum chamber, and laser stability, enabling new scientific research and potential redefinition of the second.
