Abstract Basing on homemade vacuum equipment, materials and technology a set of vacuum system with ultra high vacuum degree has beem designed and constructed for magneto optical trap of Cesium atoms. 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。
Vacuum degree of 1.2 × 10 7 Pa ( about 9.0 × 10 10 Torr) can be kept. It can meet the requirements of magneto optical trap operating in a vapor cell of Cesium atoms. 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。
