USAEL PRIMARY FREQUENCY STANDARDS.

Abstract

A primary frequency standard with the utmost in stability and accuracy is required by USAEL for research into short-term and long-term frequency stability of frequency measuring devices, rf oscillators, piezoelectric crystal-controlled equipments, and also in quartz crystal development. A good standard is vital for such research. The current USAEL standard is a cesium-beam frequency standard with a lifetime stability of 5 parts in 10 to the 12th power. This report gives a brief description of the USAEL primary frequency standard, its environmental conditions, the supporting oscillators, and the frequency distribution system. (Author)
