The life-span limitation of Cesium beam tube(CBT)is the most serious shortage in our research. Along with the development of science and technology,there is many requirements to the CBT’ s life-span. Nowadays,the life-span is the fatal problem in the CBT’ s research. In this thesis,we introduced the principle of CBT and the influence fac-tors of CBT’ s life-span,especially two factors,one is Cs Oven used up metal cesium,the other is the attenuation of the electron multiplier along with the working time increasing.
