saphir_medium.jpg The EFTS is a nonprofit 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 Institutions
