Decrease of the Frequency Shift of the Central Resonance of the Caesium-133 Quantum Frequency Standard

In the present work, several methods for decrease of the central resonance frequency shift of caesium- 133 quantum frequency standard are presented. The new implementation of the frequency synthesizer and magnetic field stabilization system for caesium atomic clock are developed. The results of experimental study of metrological characteristics for the caesium atomic clock with new frequency synthesizer and implemented magnetic field stabilization part showed improvement in daily frequency stability by 25%.
