Program, 2023

• Introduction to TF – Basic concepts and vocabulary (quality, certification, traceability etc.), and technical issues (oscillators, frequency standards, accuracy, stability, phase noise, jitter, physical environment, etc.).
• Measurement methods and experimental techniques – Spectra (phase noise and L(f), amplitude noise), variances, frequency measurement and comparison.
• Atomic clocks – Physics, traditional clocks (atomic beam, vapor cell and maser), cold atoms, optical clocks, small-size clocks.
• Oscillators – RF and microwave oscillators, cavity-stabilized lasers, optical frequency combs.
• Timing and applications – Time scales, navigation, frequency transfer and synchronization.
• Physics, applications, and trends.

Every day, the participants do real experiments and measurements

• Frequency stability and AM/PM noise,
• Data analysis
• Global Navigation Satellite System GNSS (GPS, Galileo, etc.)
• Resonators and oscillators
• Atomic clocks

This part may be the most impacted by COVID-19, if the crisis is not ended

• Visit at the Observatory of Besançon
• FEMTO-ST Laboratory Tour
• Visit at the Time Museum, Besançon downtown
• Social dinner
• Astronomy session at the Observatory (depending on weather). Observe celestial bodies, and adjust your watch to stars using the original ancient instruments

• Program and topics are decided by the Scientific Council
• All lecturers are invited by the Scientific Council
• However, suggestions from qualified people are welcome
• There is no “call for papers” addressed to the students
• There are no lectures and no posters presented by the students

Informal discussions about the research projects running in Besançon, around posters, beer and chips. This session is an opportunity to have private discussions between students, lecturers and our researchers. It helps to plan the official Friday visit, and it may open the opportunity for short private visits on specific topics in the free time during the week. Students shall not bring their own posters.
