Description
Summary:The author describes several scientific experiments requiring highly stable oscillators. It is clear from this analysis that technology has advanced to the point where concepts of relativity theory can be tested in a number of ways. He shows sigma versus tau plots for stored ion devices, for atomic hydrogen masers, and for a binary pulsar. In the discussion of experimental techniques, the H maser performance data on sigma versus tau plots are used as a basis for numerical examples.< >
