Abstract: A refrigerator port includes a sleeve and a pedestal. A pipe is drawn out from the refrigerator port. The pipe is provided with a valve. Before a cold head is pulled out, helium gas in a tank is supplied to a port space via the pipe. Accordingly, a pressure in the port space becomes the atmospheric pressure or approaches the atmospheric pressure. A pressure adjustment facility can also function when residual gas is discharged from the port space. Thus, the load of an operation of pulling out the cold head from the refrigerator port is reduced.
