Get PriceModern atomic frequency standards, including their performance, are compared quantitatively, and projections are attempted at likely future developments and performance characteristics. As in 1966, the standards principally used in technical and scientific applications are rubidium gas cell devices, cesium beam tubes, and hydrogen maser oscillators.
Get PriceAtomic Frequency Standards are the devices affording the higher precisions and accuracies in the measurement of a physical quantity. In the paper three basic spectroscopic techniques are described and the results insofar obtained with the different types of atomic standards are outlined, pointing out the contributions of the Italian Laboratories to this branch of the

Get PriceAbstract: The last comprehensive survey on atomic frequency standards was done by McCoubrey [1]. This survey reviews the more recent historical background of atomic frequency standards leading to the present developments. A discussion of the underlying physical and engineering principles is given.
Get Price2021-01-07· Statistics of atomic frequency standards Abstract: A theoretical development is presented which results in a relationship between the expectation value of the standard deviation of the frequency fluctuations for any finite number of data samples and the infinite time average value of the standard deviation, which provides an invariant measure of an important quality factor of a frequency standard.
