Summary
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 effect on the minimum refrigeration temperature. In contrast, changing the pulse tube length has a significant effect. This result suggests that heat input due to shuttle gas motion in the pulse tube is the main origin of refrigeration loss.
