Using of the millimeter wave dielectrometer for study of liquid helium dynamic characteristics

The WGM method was used in designed cryogenic dielectrometer for measurement of dielectric parameters of cryogenic liquids with small losses within the frequency range of 50-150 GHz and temperatures 0.8-300 K. The change of resonant characteristics of high-Q DDR, placed into He 4 at temperature lowe...

Zusammenfassung:The WGM method was used in designed cryogenic dielectrometer for measurement of dielectric parameters of cryogenic liquids with small losses within the frequency range of 50-150 GHz and temperatures 0.8-300 K. The change of resonant characteristics of high-Q DDR, placed into He 4 at temperature lower the lambda-transition (a superfluid state) is detected
