摘要：

The problem of developing a temperature compensation system in quantum frequency standards based on coherent population trapping is considered. The development of such a system significantly reduces the temperature coefficient of frequency (TCF), whose value is an order of magnitude higher than in rubidium frequency standards. One approach to reducing TCF is temperature compensation. The author proposes a temperature compensation method on the basis of the Zeeman effect for the shift of the actual frequency. A method for determining the minimum value of the magnetic field at which magnetically sensitive resonances have no impact on the reference resonance is considered. The performance of the quantum frequency standard both prior to and following the activation of the temperature compensation system is described.
