This paper brings out results of a measurement campaign aiming to determine the temperature coefficients of synthetic quartz elastic constants at liquid helium temperature. The method is based on the relationship between the resonance frequencies of

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 temperatures is presented. The method is based on the use of extremely high-

We present full characterisation of acoustic wave devices based on the fully synthetic crystalline material at the liquid helium temperature range { required for the design of ultra low loss mechanical systems in many areas of research including freq

Low-loss, high frequency acoustic resonators cooled to millikelvin temperatures are a topic of great interest for application to hybrid quantum systems. When cooled to 20 mK, we show that resonant acoustic phonon modes in a Bulk Acoustic Wave (BAW) q

International audience; Intrinsic frequency fluctuations with a $1/f$ power spectral density limit the short-term stability in quartz crystal ultra-stable oscillators. The physical origin of this $1/f$ noise remains not clearly explained. In this pap

International audience; Quartz crystal resonators can exhibit huge quality factors (in excess of 1 billion) at liquid helium temperature. Nevertheless, they must satisfy a set of conditions to meet this high level of resonance. With the help of exper
