NIST-F1 clock
  • eri tüüpi aatomikell Riiklikus Etalonide ja Tehnoloogia Instituudis (NIST), mis toimib Ameerika Ühendriikide peamise aja- ja sagedusetalonina
  • type of atomic clock, in the National Institute of Standards and Technology (NIST), and served as the United States' primary time and frequency standard

Usage examples
  • Tseesiumsageduskella (NIST-F1 kell) ehitamine ja katsetamine võttis aega neli aastat ning selle töötasid välja Steve Jefferts ja Dawn Meekhof NIST-i füüsikaliste mõõtmiste labori aja ja sageduse osakonnast. See etalonkell on kavas asendada uue NIST-F2 etalonkellaga, mis on ligikaudu kolm korda täpsem kui NIST-F1 kell ning plaanis on see käitada samaaegselt NIST-F1 kellaga.

cesium fountain clock
Usage examples
  • The construction and testing of the cesium fountain clock (NIST-F1 clock) took four years; it was developed by Steve Jefferts and Dawn Meekhof from the Time and Frequency Division of NIST's Physical Measurement Laboratory. There are plans to replace this standard clock with the new NIST-F2 - which is approximately three times more accurate than the NIST-F1 - and to operate it concurrently with the NIST-F1.
