The Active Hydrogen Maser technology provides the best known frequency stability for a frequency generator commercially available today. Active masers will be used when the best stability is needed in a time domain of 1 sec. to a day. At a 1-hour averaging time, the Active Maser exceeds the stability of the best known cesium oscillators by a factor of at least 100. Unlike cesium oscillators, Hydrogen Masers have no physics wear-out mechanism. They have the inherent ability to operate for 10 years, although failures earlier than 10 years can be attributed to ion pumps, the dissociator, and the hydrogen source. Even if such maintenance is needed, the costs will be a factor of 10 less than the cesium beam tube replacement, which will occur in the five to ten years life of the equipment.
