Abstract :
Results are presented of experimental and theoretical investigations for improvement of long-term frequency stability of passive atomic frequency standards. A brief review is given of parametric frequency shifts of the atomic clock transition in a cesium beam tube discriminator. The transformation of fluctuations in an atomic beam tube and in passive atomic frequency standard is considered. The investigations resulted in the improvement of the accuracy of the parameters of the frequency standard by an order of magnitude
