Gravitime Pendulum is a simple maintained pendulum in order to realize a travelling educational experiment,dedicated to scientific events for the general public, for high schools and museum institutions all over the world.Its essential aim being to sensitize the public to the metrological procedure through the operation of identificationof the acceleration of gravity by the measure of different frequencies.
A “general public” conference as part of the “Nuit des Temps” event was recorded. Please find it on the SFP YouTube channel: Gravitime Pendulum


PhD defense by Lucas Groult – July 7st 2021 at 2PM

Lucas Groult will defend his thesis on July 7th 2021, entitled: “Conception d’un piège de Paul microfabriqué pour le développement d’une horloge optique compacte, à ion piégé Yb+”, prepared at the University of Bourgogne Franche-Comté, in collaboration with FEMTO-ST and under the supervision of Yann Kersalé. The defense will be  in the amphithéâtre Jules Haag – ENSMM – 26, Rue de l’Epitaphe – Besançon.

Rodolphe Boudot (FEMTO-ST) received the 2020 EFTF Young Scientist Award

The EFTF Young Scientist Award 2020 goes to Dr. Rodolphe Boudot ,”for his outstanding contributions to the development of high-performance compact and miniature CPT atomic clocks.”
The EFTF Young Scientist Award is conferred in recognition of a personal contribution that demonstrated a high degree of initiative and creativity and led to already established or easily foreseeable outstanding advances in the field of time and frequency metrology. The award honours a person under the age of 40 at the date of the opening session of the EFTF conference.

One-year secondment : Developer in GNSS time/frequency transfer

The BIPM (International Bureau of Weights and Measures) invites applications for a one-year secondee position in the Time Department, for developments in the field of GNSS time/frequency transfer with PPP and IPPP. The position may be extended to a second year.

Applications should be sent by 20 June 2021.

See more information on duties, employment conditions of such a secondee position, expected qualifications and experience, as well as on the application process in the announcement “One-year secondment – Developer in GNSS time/frequency transfer” at .

The BIPM is located at the Pavillon de Breteuil, Sevres, France, situated in the outskirts of Paris. The Time Department computes and disseminates the international reference time scale Coordinated Universal Time (UTC), and provides traceability to the international system of units (SI) to local realizations of UTC maintained in national institutes.

EFTS 2021 – European Frequency and Time Seminar

The EFTS is a no-profit intensive full-week seminar intended to provide education and training with lectures and lab sessions. It targets the broadest audience: Engineers, Ph.D. students, post-docs, young scientists, newcomers, etc.
This seminar is unique in the following:

  • Broad spectrum of topics related to time and frequency
  • Balance between academic and applied issues
  • Broad target audience, yet keeping high level education
  • Lab sessions. The participants work themselves in small groups with a wide range of instruments made available.

The high level of training is guaranteed by the world-class Scientific Council and lecturers from the major European and International Institution.
