Aspects of functioning, National (state primary) standard of units of time and frequency, further NDETU TF-01-2021 and maintenance of metrological characteristics at the appropriate level are considered. For the purpose of proper functioning, the National (state primary) standard of units of time and frequency, further NDETU TF-01-2021 maintaining metrological characteristics at the appropriate level, the standard includes hydrogen frequency keepers, measure Ch1-80, during the use of which there is a need for complex maintenance one of the key elements of the hydrogen reservoir. Practical aspects of technical maintenance and service of one of the key elements of the hydrogen frequency storage device, measure Ch1-80, magnetic discharge ion-heterogeneous pump are considered. The design and principle of operation of the magnetic discharge ion-heterogeneous pump, the design and the principle of operation of this type of pumps as part of the measure Ch1-80 are given.
The condition of the equipment is analyzed, the measures on restoration of metrological characteristics of measure Ч1-80 and other standards of time and frequency of this type are offered and executed.
Ways to further improve the metrological characteristics of both the National (state primary) standard of units of time and frequency, NDETU TF-01-2021 and measures of time and frequency Ch1-80
