A Comparison of Cs Fountain Primary Frequency Standards
Thomas E. Parker
There are currently 9 cesium fountain primary frequency standards reporting calibrations of TAI to the Bureau International des Poids et Measures (BIPM). An investigation has been carried out using data from the BIPM publication Circular T to evaluate the frequency offsets among these standards and to determine if these offsets are consistent with the stated uncertainties. The results of this investigation show that, overall, the standards are in very good agreement with each other.
