A recent series of papers by Gifford and Longsworth [1–3] describe a simple refrigeration device (illustrated schematically in Fig. 1) which has potential applications. They have called this device a “pulse tube refrigerator.” The pulse tube refrigerator consists of a regenerator connected in series with an open tube, which is the pulse tube. The void volume of the regenerator is V R and the void volume of the pulse tube is V pt . Gas enters and leaves the device through the warm end of the regenerator which is at a temperature T W . The volume V h , which is connected to the end of the pulse tube, is maintained at a temperature T h by means of cooling medium. In general, at least for the simple pulse tube, both T h and T W will be approximately at room temperature.
