The absolute frequency of the 87Sr optical clock transition
The absolute frequency of the S0–P0 clock transition of 87Sr has been measured to be 429 228 004 229 873.65 (37) Hz using lattice-confined atoms, where the fractional uncertainty of 8.6 × 10−16 represents one of the most accurate measurements of an atomic transition frequency to date. After a detailed study of systematic effects, which reduced the total systematic uncertainty of the Sr lattice ...
متن کاملPrimary Atomic Frequency Standards at NIST
The development of atomic frequency standards at NIST is discussed and three of the key frequency-standard technologies of the current era are described. For each of these technologies, the most recent NIST implementation of the particular type of standard is described in greater detail. The best relative standard uncertainty achieved to date for a NIST frequency standard is 1.5×10(-15). The un...
متن کاملSecond Generation Cesium Fountain Primary Frequency Standards at NIST
NIST is currently investigating the design of a second-generation cesium-fountain primary frequency standard. The design goals of this standard include an ultimate frequency inaccuracy of δf/f < 10 and achievable stability better than σy(τ) < 10/τ. This standard is expected to eventually replace NIST-F1, the current U.S. primary frequency standard [1]. In the context of reaching frequency uncer...
