A new generation of hydrogen quantum frequency and time standards at Nizhnii Novgorod Kvarts Instrument Building Research Institute

  • Published:
Measurement Techniques Aims and scope

This paper reports on the development of hydrogen quantum standards of frequency and time of a new generation, including the Ch1-90 active laser and the Ch1-91 passive laser. Descriptions are given of the block diagrams and construction, and technical characteristics are quoted together with experimental tests on the frequency instability. Unique metrological characteristics have been obtained for standard hydrogen instability of frequency per 1 day (the mean standard deviation) for the Ch1-90 and Ch1-91 are, respectively, 3·10–16 and 2.5·10–15, which allows one to meet the requirements of the standard state basis for the precision time and frequency.

Additional information

The editors of the journal Izmeritel’naya Tekhnika continue the publication of articles from leading scientists at the Federal Scientific Production Center represented by the Kvarts Nizhnii Novgorod Instrument Building Rese arch Institute, which in this year reaches an age of 60 years (for start see Measurement Techniques, No. 9, 2009). A major direction of work lines at the Kvarts Center is related to measurements of time and frequency. This topic in the main is concerned with the articles given below.
