The Ion Storage Technique For Application In Frequency Standards PDF Download

Excerpt from The Ion Storage Technique for Application in Frequency Standards At present the most accurate frequency standard is the cesium 1m tube. This fact is widely recognized, and is reflected in the ernational agreement of 1967 which bases the definition of the second the transition frequency of cesium. Naturally there is a constant nand for a more accurate realization of this definition. In addition quency standards of extreme precision are needed in applications zh as navigation and communication systems, air traffic control stems, and various Special military systems, Looking aheadlit therefore appears both necessary and desirable find ways and means to meet these demands. The cesium beam tube already at a very advanced stage of technical development. An uracy capability of the order of seems to be a limit for cesium 1m tubes which will prove difficult to surpass. Alternative approaches are being sought which hold the promise significantly exceeding the accuracy performance of cesium beam les (hellwig, to be published They include the hydrogen maser eppner, et al atomic and molecular beam tubes such as llium (beehler and Glaze, 1966) and hydrogen storage (hellwig, rared and optical devices such as the methane saturated absorption 1rger and Hall, and the ion storage technique (dehmelt.
