CRYOGENIC REGENERATOR MANUFACTURING METHOD AND CRYOGENIC REGENERATOR

摘要

A method of manufacturing a cryogenic regenerator includes the steps of supplying helium gas to a helium gas sealing tube having a front end portion and a rear end portion that are open; sealing the rear end portion of the helium gas sealing tube; cooling the helium gas sealing tube and filling the helium gas into the cooled helium gas sealing tube from a helium gas supplying unit; and sealing the front end portion of the helium gas sealing tube after the helium gas sealing tube is filled with the helium gas.
