Since a piston does not exist in expansion space like the conventional cryocoolers, a pulse cryocooler cannot evaluate a performance in geometry. However, it becomes a very important factor to understand a motion of gas in expansion space, in order to raise a cooling performance. It considers as the simple method of understanding the cooling generating mechanism of a pulse tube cryocooler gas in a pulse tube is judged a solid piston (gas piston), and there is the equivalent PV method which computes work in expansion space. However, the work flow within an actual pulse tube of the ability of it to be able to express by the equivalent PV method is not certain. As the beginning, the compression machine (phase shifter) was installed at the pulse tube hot-end, and evaluation examination of the work flow in the boundary was measured and carried out at it, in this report.
