Installation of Relative Acoustic Gas Thermometry in the Low Temperature Range from 4.2 to 80 K

A relative acoustic gas thermometry unit for reproducing and transmitting the unit of thermodynamic temperature, i.e., kelvin, in the low temperature range 4.2–80 K was developed and tested. The proposed apparatus differs from previously developed relative acoustic gas thermometry devices in terms o...
