Abstract. In recognition of the October 1964 declaration of the International Committee of Weights and Measures that the physical measurement of time be based on a particular transition between two hyperfine levels in the ground state of cesium 133, a review of the characteristics of cesium beam atomic frequency standards is presented.Microchip (Microsemi, Symmetricom's) Cesium beam tube replacement services offer you both time and cost savings – Don't risk an unscheduled service interruption. Don't risk an unscheduled service interruption. Unlike hydrogen or rubidium atomic clocks, the cesium will be consumed during normal operation and the tube may only last 8 - 15 years.

They play a key role in the long-term stability of cesium beam atomic clocks. After 75 days of continuous running and measurement, we released the 5-day stability results (7×10-15 Allan deviation) of our optically pumped cesium beam atomic clock. To the best of our knowledge, this is the best 5-day stability result ever reported for compact ...Cesium beam interacts with microwave in the separated oscillating cavity. This process is called Ramsey oscillation. The transition excited by the microwave is the core of cesium beam atomic clock. The frequency of microwave is near 9192631770 Hz. At the same time, the microwave is required to have pure frequency and small phase noise.
