Characterization of the Main Frequency Shifts for the Brazilian 133Cs Atomic Beam Frequency Standard
In order to evaluate an atomic clock, it is important to determine the main frequency shifts caused by external fields, device imperfections, etc. Scanning the frequency of the main oscillator, the Ramsey fringe is obtained and used to determine the main shifts. The gravitational shift (10−17), second order Doppler (1.65×10−13), Black-Body radiation shift (2.9×10−14), quadratic Zeeman effect (5...
متن کاملCollisional frequency shifts in 133Cs fountain clocks.
We present a theoretical analysis of the density dependent frequency shift in Cs fountain clocks using the highly constrained binary collision model described by Leo et al. [Phys. Rev. Lett. 85, 2721 (2000)]. We predict a reversal in the clock shift at temperatures near 0.08 microK. Our results show that s waves dominate the collision process. However, as a consequence of the large scattering l...
متن کاملSome Accuracy Limiting Effects in an Atomic Beam Frequency Standard
The accurate resonance frequency of the transition (F, M ) = (4, 0) ++(3 , 0) in the ground state of cesium-l33 is expressed In the form of an operational equation f o r an atomic beam spectrometer. Emphasized are the terms in this equation which correct for the beam direction dependence and radiation field dependence of measured resonance frequencies: F where i and j refer to opposite beam dir...
متن کاملHigh-accuracy calculation of the blackbody radiation shift in the 133Cs primary frequency standard.
The blackbody radiation (BBR) shift is an important systematic correction for the atomic frequency standards realizing the SI unit of time. Presently, there is controversy over the value of the BBR shift for the primary 133Cs standard. At room temperatures, the values from various groups differ at the 3x10(-15) level, while modern clocks are aiming at 10(-16) accuracies. We carry out high-preci...
