Second sound attenuation in a liquid helium counterflow jet
The attenuation of a beam of high frequency second sound traversing a counterflow jet in liquid helium has been measured in the temperature range 1.6 to 2.06°K. Combined use of thin film superconducting thermometers with specially developed low noise amplifiers allowed a temperature resolution of...
