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…
PHARAO Laser Source Flight Model: Design and Performances
Thomas Lévèque, Benoit Faure, François-Xavier Esnault +11
In this paper, we describe the design and the main performances of the PHARAO laser source flight model. PHARAO is a laser cooled cesium clock specially designed for operation in s…
Testing local position and fundamental constant invariance due to periodic gravitation and boost using long-term comparison of the SYRTE atomic fountains and H-masers
M. E. Tobar, P. L. Stanwix, J. J. McFerran +8
The frequencies of three separate Cs fountain clocks and one Rb fountain clock have been compared to various hydrogen masers to search for periodic changes correlated with the chan…
Experimenting an optical second with strontium lattice clocks
R. Le Targat, L. Lorini, Y. Le Coq +17
Progress in realizing the SI second had multiple technological impacts and enabled to further constraint theoretical models in fundamental physics. Caesium microwave fountains, rea…
Time and frequency transfer with a microwave link in the ACES/PHARAO mission
P. Delva, F. Meynadier, P. Wolf +2
The Atomic Clocks Ensemble in Space (ACES/PHARAO mission), which will be installed on board the International Space Station (ISS), uses a dedicated two-way Micro-Wave Link (MWL) in…
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.…
