摘要：

Ion traps are a rugged, proven technology that supports high-performance and manufacturable time keeping solutions. Our approach to this implementation is based on the 12.6 GHz hyperfine transition of Yb-171(+) ions confined in a linear Paul trap. We report an instability of 6 x 10(-13) tau(-1/2) up to averaging time tau = 100 s in the presence of buffer gas, which is a 40% improvement from our previous report. The ion trap is implemented in a 2U-compatible enclosure, which is characterized by ion storage times >95 days and Allan deviation down to 4 x 10(-15) at tau = 2x 10(5) s.
