Beam Trajectory in Cesium-Beam Primary Frequency Standard and Its Influence on Frequency Stability and Shift : Techniques, Instrumentations and Measurement

概要

論文の詳細を見る
A simulation of a cesium-beam primary frequency standard, using a beam-trajectory method, is carried out. In the calculations, the following assumptions are made: 1) the beam collimator has a finite area instead of a point source, 2) the effective dipole moment is dependent on the position in the hexapole magnet, 3) the atoms rotate about a beam axis, 4) the beam trajectory falls due to gravity, 5) the first-order Doppler effect and distributed cavity phase difference in the interaction regions of the Ramsey cavity apply. By evaluating the equations and the experimental results, the influence of beam trajectory on beam efficiency, frequency stability and microwave power-dependent frequency shift are examined.
