Atomic fountains and optical clocks at SYRTE: status and perspectives
M. Abgrall, B. Chupin, L. De Sarlo +9
In this article, we report on the work done with the LNE-SYRTE atomic clock ensemble during the last 10 years. We cover progress made in atomic fountains and in their application t…
Contributing to TAI with a Secondary Representation of the SI Second
Jocelyne Guéna, Michel Abgrall, André Clairon +1
We report the first contribution to the international atomic time (TAI) based on a secondary representation of the SI second. This work is done with the LNE-SYRTE FO2-Rb fountain f…
Demonstration of a Dual Alkali Rb/Cs Atomic Fountain Clock
J. Guéna, P. Rosenbusch, Ph. Laurent +7
We report the operation of a dual Rb/Cs atomic fountain clock. 133Cs and 87Rb atoms are cooled, launched, and detected simultaneously in LNE-SYRTE's FO2 double fountain. The dual c…
Improved tests of Local Position Invariance using 87Rb and 133Cs fountains
Jocelyne Guéna, Michel Abgrall, Daniele Rovera +5
We report tests of local position invariance based on measurements of the ratio of the ground state hyperfine frequencies of 133Cs and 87Rb in laser-cooled atomic fountain clocks.…
Progress in Atomic Fountains at LNE-SYRTE
Jocelyne Guéna, Michel Abgrall, Daniele Rovera +10
We give an overview of the work done with the Laboratoire National de Métrologie et d'Essais-Systèmes de Référence Temps-Espace (LNE-SYRTE) fountain ensemble during the last five y…
