Abstract
An apparatus for measuring the refrigeration capacity of cryopump refrigerators including the pulse tube type being developed domestically and the GM type has been designed, manufactured, and tested. The refrigeration capacity of a commercial refrigerator was evaluated for confirming the measurement procedure and the operation performance of the apparatus. The measured 2-D refrigeration capacity chart showed the intrinsic characteristics of the refrigerator model used in the experiment. In this paper, design specifications and test results of the refrigeration capacity measurement system is reported and discussed.
