摘要
铯原子喷泉钟在守时系统起校准作用。介绍了铯原子喷泉钟NTSC-F1的4个子系统及运行参数,与氢钟比对测量获得了NTSC-F1的频率稳定度性能,实现了系统不确定度的初步评定,给出了各频移项的频移量和不确定度,并对NTSC-F1的改进进行了介绍。
Cesium fountain clock play an important role in time-keeping. The four sub systems and operation procedure for NTSC-F1 are introduced in this paper. The frequency stability of NTSC-F1 is shown compared to hydrogen maser. A preliminary assessment for the uncertainty of the system has been completed, in which the frequency shifts and their uncertainties for various frequency shift terms are evaluated. The improvement of NTSC-F1 is introduced too.
