โฆ Synopsis
The pulse tube reported in this paper is 5 mm in inner diameter and 50 mm in length with an effective tube volume of about 0.4cm3. The coaxial design is used to minimize its dimensions and nylon tube is used to decrease heat transfer between the pulse tube and the surrounding regenerator.
It was operated at a frequency of 11 Hz with a filling pressure of 1.19 MPa and was obtained at 159.4 K as the lowest temperature.
