A new method of probing mechanical losses of coatings at cryogenic temperatures
Serge Galliou, Samuel Deléglise, Maxim Goryachev +14
A new method of probing mechanical losses and comparing the corresponding deposition processes of metallic and dielectric coatings in 1-100 MHz frequency range and cryogenic temper…
About Quartz Crystal Resonator Noise: Recent Study
Fabrice Sthal, Serge Galliou, Joël Imbaud +4
The first step, before investigating physical origins of noise in resonators, is to investigate correlations between external measurement parameters and the resonator noise. Tests…
Advanced bridge instrument for the measurement of the phase noise and of the short-term frequency stability of ultra-stable quartz resonators
Fabrice Sthal, Xavier Vacheret, Patrice Salzenstein +3
High-stability quartz oscillators are needed in a number of space applications. A short-term stability of parts in 10^{-14} [Allan deviation σy(τ) ] is sometimes required, for inte…
Development of a 5 MHz frequency difference pre-multiplier for a short term frequency stability bench of the oscillators
Patrice Salzenstein, Xavier Jouvenceau, Xavier Vacheret +2
This paper reports the realization of a 5 MHz frequency difference x10 pre-multiplier, developed in the laboratory to replace an obsolete one. The principle we chose is to synthesi…
