High accuracy evaluation of Cenam's primary frequency standard-second order Doppler shift

摘要

The Centro Nacional de Metrologia in Mexico has developed an optically pumped cesium beam frequency standard, the CsOP-1. At the present moment have been analyzed the major sources of systematic effects and evaluated the corresponding frequency shifts in the CsOp-1. In this work we reevaluate the second order Doppler shift by taking into account the modulation parameter.
