Cs-He OPTICALLY PUMPED MAGNETOMETER - THE REFERENCE GAUGE OF MAGNETIC INDUCTION FOR NATIONAL METROLOGICAL CENTRES

摘要

This paper presents the results of improvement and manufacture of prototype models of the Cs-He converters for precise magnetic measurements and development of a new type of a Cs-He magnetometer for metrological purposes to be used as a standard measuring device. The MQCH-03 Cs-He magnetometer has been tested in accordance with requirements imposed by metrological application and has the highest absolute accuracy. Such an approach to the design of a Cs-He magnetometer resulted in an instrument with unique metrological characteristics. The majority of the National Metrological Centres and leading foreign firms ( Sintrex, Gem Systems – CANADA ; Geometrics – USA ) producing magnetometers have no similar reference Cs-He converters and magnetometers.
