摘要

我们正在NIST开发一个小型激光冷却Cs喷泉，目标是实现卓越的短期稳定性/spl sigma//sub y/(/spl tau/)/spl ap/2/spl times/10/sup -14//spl tau//sup -1/2/，长期稳定性/spl ap/10/sup -15/。虽然该设备的设计不是为了达到NIST主要频率标准NIST- f1的精度，但这个小型便携式系统将被证明是具有中等精度的本地振荡器。我们将讨论该频率标准的性能目标、设计理念、现有的物理包和未来的方向。

Development of a miniature laser-cooled Cs fountain frequency standard at NIST

We are developing a small laser-cooled Cs fountain at NIST with the goal of achieving exceptional short-term stability of /spl sigma//sub y/(/spl tau/)/spl ap/2/spl times/10/sup -14//spl tau//sup -1/2/ with a long-term stability of /spl ap/10/sup -15/. Although this device is not designed to achieve the accuracy of the NIST primary frequency standard NIST-F1, this small, portable system will prove valuable as a local oscillator with intermediate accuracy. We discuss the performance goals of this frequency standard, the design philosophy, the existing physics package, and future directions.
