The heat input towards the cold end of a pulse tube refrigerator is studied using combinations of two regenerators and two pulse tubes of different lengths. The temperature gradient in the pulse tube or regenerator is altered by changing the length. Changing the regenerator length produces almost no

To investigate how to reach 4 K using a pulse tube and the best multiple staging configuration for the pulse tube, experiments were performed on several types of singlestage pulse tube refrigerators coupled with a Gifford-McMahon cryocooler. The minimum temperature obtained at the cold end of the pu
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 op
A two-stage pulse tube refrigerator in combination with a rotary valve and a valved compressor has been constructed. Its performance and the effects of the operating parameters were investigated. A minimum temperature of 11.5 K and a cooling capacity of 1.3 W at 20 K were obtained at a frequency of
