In this study, we investigate a concept that can be used to improve the magnetic field homogeneity in a microwave cavity applied in a novel, high-performance atomic frequency standard. We show that by modifying the boundary conditions in the case of a loop-gap geometry, a good improvement of the field homogeneity can be obtained. Such a design demonstrates high potential to improve the frequency stability; it is compact and hence suitable for a future generation of compact, high-precision frequency standards based on vapor cells and a pulsed optical pumping (POP) regime (POP atomic clocks).

Theory And Experiment

Momentum transfer during the resonant interaction between moving atoms and surface waves is calculated using a semi-classical method. Results show a greater Doppler shift than the one obtained in similar analysis with a plane homogeneous wave interacting with moving atoms. In order to measure such a small frequency shift, an atomic clock technique is used (accuracy: 10−10). An appropriate choice of surface wave frequency is the centimetre wavelength. The ΔF = 1, Δm = 0 transition in 87Rb is used and detected by the well-known optical pumping method.Experimental results are obtained for two different Rb atom speeds and compared with theoretical values.
