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
We designed and constructed a dynamic experimental apparatus to measure the instantaneous velocity and pressure in the multi-bypass pulse tube refrigerator (MPTR). Some experimental results of the instantaneous measurements of velocity and pressure in an MPTR with two-bypass tubes during actual oper
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
