Abstract
We have developed a set of evaluation tools whereby all of the known systematic effects are evaluated by means of leveraged experiments not involving, or limited by, precision frequency measurements. This both speeds the evaluation process and greatly reduces the "combined standard uncertainty, extending the operational life of thermal-beam technology.
