In this study, the performance of the chiller was first determined using a circular pulse tube made of acrylic, which is similar to the actual machine. After that, we attempted to take a Schlieren image of the circular pulse tube, but the curvature of the circular tube was too large to take a Schlieren image. Therefore, we attempted to improve the refrigeration capacity by switching back from a circular pulse tube to a rectangular pulse tube and changing the experimental conditions.
