Abstract

The invention relates to a technique for measuring at microwave frequencies and provides an increase in resolution and measurement accuracy. The device contains an atomic beam tube 1, a microwave generator 9, and a transiental waveguide (SEM) 10 for accommodating the test fluid. The atomic beam tube consists of a source of 2 beams of atoms, deflecting magnets 3, microwave resonator 4, collector 6, magnetic screen 7 and vacuum body 8. Microwave resonator 4 is a measuring resonator. It is connected through a diaphragm, made at its end, with the RIS 10. Filling the RR 10 with the test liquid leads to a change in the resonant frequency of the microwave resonator 4 and the shape of the spectral line of the atomic transition. From the measured values of the shift of the resonant frequency and the quality factor of the spectral line, the active and reactive components of the impedance associated with the diell are calculated. fluid parameters. 1 il.

my fluid leads to a change in the resonant frequency of the measuring resonator and the shape of the spectral line of the atomic transition. From the measured values of the shift of the resonant frequency and the quality factor of the spectral line, the active and reactive components of the impedance associated with the dielectric parameters of the fluid are calculated.
