Advances in Development of Quartz Crystal Oscillators at Liquid Helium Temperatures

Autor: Goryachev, Maxim, Galliou, Serge, Imbaud, Joël, Abbé, Philippe

Publikováno v: Cryogenics, 57, 104-112 (2013)

This work presents some recent results in the field of liquid helium {bulk acoustic wave} oscillators. The discussion covers the whole development procedure starting from component selection and characterization and concluding with actual phase noise

Investigation on flicker noise of overtones and anharmonic modes of ultra-stables quartz crystal resonators

Autor: Pokharel Alok, Cibiel Gilles, Imbaud Joel, Sthal Fabrice, Esnault Francois-Xavier

Publikováno v: 2017 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFC).

In this paper, prototypes of SC-cut resonators with 5 MHz resonant frequency are presented. The resulting short-term stability of some resonators has been measured lower than 8·10−-14 in terms of Allan standard deviation. The results are compared

Highly-stable metrological thermostat for active characterization of resonators with automatic turnover point settings

Autor: Sthal Fabrice, Vorobyev Nikolay, Imbaud Joel, Abbe Philippe

Publikováno v: 2014 European Frequency and Time Forum (EFTF).

In this paper, we describe an original digitally controlled double thermostat system for the quartz crystal oscillator that allows setting the turnover point of crystal oscillator automatically and its characterization. The oscillator optimization wa
