摘　　要：小型磁选态铯原子钟性能高、应用广,目前产品严重依赖进口。报道了一款国产的小型磁选态铯原子钟LIP Cs3000C,其束光学采用了单束的S型方案。LIP Cs3000C铯钟的频率稳定度测试结果为:5.0×10^(-12)/s,3.5×10^(-12)/10s,8.5×10^(-13)/100s,2.7×10^(-13)/1ks,8.5×10^(-14)/10ks,2.7×10^(-14)/100ks。通过分析影响寿命的因素,预计该钟的寿命为5年。LIP Cs3000C铯钟的成功研制为实现高性能铯钟的国产化替代奠定了基础。At present,the commercial compact magnetic-selected Cs clocks with high performance are heavily dependent on imports. A magnetic-selected cesium atomic clock LIP Cs3000C developed in our laboratory is reported in this article, in which we use a S-type and single beam optical scheme. The test results of the clock are as follows：5.0×10^-12/s,3.5×10^-12/10s,8.5×10^-13/100s,2.7×10^-13/1 ks,8.5×10^-14/10ks and 2.7×10^-14/100ks ks. It is expected that the life of the clock will be more than 5 years by analyzing the related factors. The successful development of the LIP Cs3000C laid the foundation for the localization of high performance cesium clocks.
