The Italian primary frequency standard IEN-CsF1 was evaluated for accuracy, considering frequency shifts and comparison with international atomic time. This research ensures precise timekeeping and supports global time standards.

Area of Science:

  • Metrology
  • Atomic Physics
  • Frequency Standards

Background:

  • Accurate timekeeping is crucial for scientific research and global synchronization.
  • Primary frequency standards are the basis for national and international time scales.
  • Cesium fountain clocks represent the state-of-the-art in primary frequency standards.

Purpose of the Study:

  • To report the accuracy evaluation of the Italian primary frequency standard IEN-CsF1.
  • To detail the frequency shifts and corrections applied to the standard.
  • To compare the performance of IEN-CsF1 with other international frequency standards.

Main Methods:

  • Accuracy evaluation of the IEN-CsF1 cesium fountain.
  • Identification and correction of systematic frequency shifts.
