| 中文摘要 | it is the first time in china that the phase variations and phase shift of microwave cavity in a miniature rb fountain frequency standard are studied, considering the effect of imperfect metallic walls. wall losses in the microwave cavity lead to small traveling wave components that deliver power from the cavity feed to the walls of cavity. the small traveling wave components produce a microradian distribution of phase throughout the cavity ity, and therefore distributed cavity phase shifts need to be considered. the microwave cavity is a te011 circular cylinder copper cavity, with round cut-hole of end plates (14mm in diameter) for access for the atomic flux and two small apertures in the center of the side wall for coupling in microwave power. after attenuation alpha is calculated, field variations in cavity are solved. the field variations of the cavity are given. at the same time, the influences of loaded quality factor ql and diameter/height (2a/d) of the microwave cavity on the phase variations and phase shift are considered. according to the phase variation and phase shift of microwave cavity we select the parameters of cavity, diameter 2a = 69.2mm, height d = 34.6mm, ql = 5000, which will result in an uncertainty delta(delta f / f0 ) < 4.7 x 10(-17) and meets the requirement for the miniature rb fountain frequency standard with accuracy 10(-15). |
