2026 EFTS
The 14th European Frequency and Time Seminar
Monday, June 29, to Friday, July 3
Besancon, France
The EFTS is a nonprofit intensive full-week seminar intended to provide education and training with lectures and lab sessions. It targets a broad audience: Engineers, Ph.D. students, post-doctoral fellows, young scientists, newcomers, etc.
The EFTS is held every year at the beginning of Summer at the FEMTO-ST Institute.
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, keeping high level education
- Hands-on 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 Institutions.
New, since 2026
- We plan to accept up to 60 participants, all accessing 7.5 H labs in small grpups.
- A small fraction of such places may be reserved, based on scientific criteria.
- There are two tracks: Metrology (max 24 people) and Research (max 36 people).
- The tracks differ in two of the three 2.5-H lab sessions.
- All lectures and one lab session are the same.
- Applicants express their preference, but they may be assigned to the other track depending on the availability of places.
- Companies/Institutions sending multiple participants shall indicate a correspondant, our unique interlocutor if we need to arbitrate in applications.
- The full-labs (12H), half-labs (6H) and no-labs options are suppressed.

Thanks
The EFTS can happen only thanks to the good will and to the voluntary work of numerous people. None of us has been paid for this additional burden ever, and sometimes lecturers choose to travel on their own research grants. As the intellectual pursuits of academia are largely in the realm of the gift economy, by far the greatest reward is found in the appreciation of one's work by one's colleagues.
The EFTS is kindly hosted by SUPMICROTECH / ENSMM.
