Available in PDF, EPUB and Kindle. Book excerpt: A tutorial discussion of the physical basis of atomic frequency standards is given.These principles are then related to the conditions under which an atom can be used as the working substance of a stable and accurate frequency standard.The three primary examples of atomic frequency standards--the hydrogen maser, the cesium beam, and the rubidium gas cell--are then discussed in terms of these principles and conditions.The functions of the fundamental parts of each device become apparent through this development.(Author).
