Vibrations of Cantilever Beams:

 · However, the same beam coated with ZnO will have its fundamental frequency,, shift from Hz to Hz. Any oscilloscope can be used to measure the beam's vibrations, see Figure 6, above. If enough data points are taken, a Fourier transform of the signal can measure frequency shifts even as small as Hz. Therefore, the frequency shift can then be known with high accuracy, and the ...

Since its introduction 7 years ago, the HewlettPackard cesium beam frequency standard has been installed in many national laboratories. At the present, this standard represents over 70% of the number of atomic clocks reported to the Bureau International des Poids et Mesures (BIPM). Many of these are monitored on a continuous basis. Data from 160 clocks HP currently reported by BIPM is used to ...

 · It is demonstrated that frequency pulling by Δm=±1 hyperfine σ transitions, here called Ramsey pulling, is a real calculable effect in atomic beam frequency standards. An analytic expression for the effects of Ramsey pulling is derived using perturbative techniques for the driving σ transitions, while treating the primary π transitions exactly.
