立足于国产材料、真空设备和技术，设计、建立了一套用于铯原子磁光阱的超高真空系统。整个系统结构紧凑、性能稳定、操作方便，其真空度可保持在１．２×１０－７Ｐａ（约９．０×１０－１０Ｔｏｒｒ）左右，可满足直接工作在铯原子汽室中的磁光阱的要求。 Based on the domestic materials, vacuum equipment and technology, design, set up a set of ultra-high vacuum system for cesium atomic magneto-optical trap. The whole system has the advantages of compact structure, stable performance and convenient operation. The vacuum degree can be kept at about 1.2 × 10-7Pa (about 9.0 × 10-10 Torr), and the magneto-optical trap can be directly operated in the cesium atom chamber Request.
