Neuchâtel expects 450 Time and Frequency specialists to attend the EFTF2024

The European Frequency and Time Forum (EFTF) is a congress in the time & frequency domain. 450 researchers and technologists from academia to research centers, metrology laboratories and manufacturers, service providers, operators, application developers, defense timing and standards bodies attend a series of plenary and invited sessions, oral and poster presentations, and a dynamic industry exhibit.

Time masters meet in Neuchâtel

Organized collaboratively by six partners representing academia, research, and industry – FSRM (Swiss Foundation for Research in Microtechnology), Time Frequency Laboratory (LTF) of the University of Neuchâtel, CSEM, Oscilloquartz, Safran and SFMC (Société française des microtechniques et des chronométries) – the EFTF 2024 promises an engaging blend of oral and poster scientific presentations, along with a dynamic commercial exhibition. Scientists, engineers, and specialists from around the globe will converge in Neuchâtel for the 37th edition of this renowned event. 

Professor Gaetano Mileti, co-president of the organizing committee and deputy director with the Time and Frequency Laboratory (LTF) at the University of Neuchâtel (UniNE), underscores the significance of the EFTF: “Since the inception in 1987, the Forum has grown substantially and has become a world renown conference. Every second year, EFTF meets with its North American counterpart the International Frequency Control Symposium (IFCS). In 2024, the EFTF returns to Neuchâtel after 10 years abroad. Our city, with its strong presence in time and frequency in research and industry is the ideal backdrop for this gathering.” 

Sylvain Karlen, Group Leader for Quantum Technologies in CSEM's Instrumentation Business Unit, emphasizes their commitment: "Helping organize and participate in the EFTF allows us to showcase our activities and foster valuable exchanges with academic and industrial partners."

The Redefinition of the Second 

Conference highlights comprise the Plenary Session dedicated to the Redefinition of the Second, which will be open to the public. Esteemed specialists including Noël C. Dimarcq (CNRS and CIPM, President of the Bureau des Longitudes, France), Sébastien Bize, (LNE-SYRTE, France), and Davide Calonico, (INRIM, Italy) will share insights. The Women in Science Session will welcome Patrizia Tavella, Director of the Time Department at BIPM (International Bureau of Weights and Measures, France). 

Neuchâtel: A cradle of universal time 

The Neuchâtel region boasts exceptional expertise in the field of time and frequency. Its chronometrical Observatory, established in 1858, gained global recognition for Swiss precision. For decades, it broadcast the 12:30 time signal on Swiss radio. Three centuries ago, its founder and director Adolphe Hirsch proposed the universal time adoption and a reference meridian (Greenwich). Today the region hosts industries specializing in watchmaking, atomic clocks, microtechnology, oscillators, and high-performance lasers. Neuchâtel’s globally acknowledged expertise in relation to time and frequency underscores its proficiency in producing small, complex, and reliable precision components. These high-value components are integral to numerous products sold worldwide. 

About the Time Frequency Laboratory of University of Neuchâtel 

The Time-Frequency Laboratory (LTF) explores and pushes back the frontiers in the fields of time-frequency, optical metrology and ultrafast science and technology. LTF research focuses on the development of atomic clocks and miniature quantum sensors for space applications. The LTF has also helped Switzerland to join the limited number of countries that actively participate to the definition of the international atomic time (TAI – Temps atomique international). This research has involved developing primary frequency standards, and the unique atomic fountain clock FOCS-2 that operates with a continuous beam of cold cesium atoms. The LTF presently contributes to the effort of the BIPM (Bureau international des poids et mesures) and the international community towards a redefinition of the second. https://www.unine.ch/ltf/home.html.

About the SFMC 

Established in 1931, the SFMC is committed to reinforce the relations between the actors of watchmaking, micro-technology, and time-frequency, in order to promote the science of chronometry. In collaboration with the Swiss Foundation for Research in Microtechnology (FSRM), SFMC created the European Frequency and Time Forum (EFTF) in 1987. This international conference was held alternately in Besançon and Neuchatel until 1992. Then, it has been hosted in other European cities. Since 1999, it has been regularly associated with the IEEE International Frequency Control Symposium (IFCS), at first on a quadrennial base, and thereafter on a biennial base. As a legal entity of the EFTF, the SFMC has organized 4 EFTF and IFCS/EFTF conferences in Besançon and supports the organization of these conferences in other locations, especially by supporting the student attendance, the scientific awards, and setting the agreements between EFTF and IEEE, necessary to publish EFTF proceedings and to organize the joint conferences.
