Abstract: This paper introduces the progress of the commercialization of the compact magnetically selected cesium atomic clock.The contents include performance,reliability and lifetime of cesium clocks,which have attracted widespread attentions.It is pointed out that the reason why the performance is guaranteed is that the single-beam optics is used in cesium beam tube,and the digital technology in circuit.Some failures and solutions in the early stage of commercialization are given,as well as the environmental adaptability test to further improve the reliability.The paper also discusses the evaluation method of lifetime of the electron multiplier,and puts forward the lifetime evaluation formula which is applicable to some cesium clocks.Finally,some works that need to be further explored in the process of commercialization are pointed out.The methods introduced in this article is not only helpful for the commercialization of magnetically selected cesium atomic clocks,but also has reference value for optically pump cesium clocks and even other types of atomic clocks.
