Frequency Standards and Metrology

The Symposium on Frequency Standards and Metrology in Ancona 1988 was the most recent in a series of meetings which review the progress and state of the field every five years. These proceedings give a comprehensive review in 58 invited papers and 45 poster contributions of: - current work on established and new microwave standards, - the frequency stabilization of lasers, - frequency synthesis as the connection between standards of differing frequency, - trapping of neutral and ionized atoms as a future means to achieve the most stable and accurate standards. Contributions highlight the importance of precise frequency measurement for advanced experimental work in quantum and gravitational physics.
