Summary:An object of the present invention is to reduce a load of an operation of pulling out a cold head from a refrigerator port.A refrigerator port 14 includes a sleeve 24 and a pedestal 34. A pipe 50 is drawn out from the refrigerator port 14. The pipe 50 is provided with a valve 52. Before a cold head 16 is pulled out, helium gas in a tank 58 is supplied to a port space 42 via the pipe 50. Accordingly, a pressure in the port space 42 becomes the atmospheric pressure or approaches the atmospheric pressure. A pressure adjustment facility 48 can also function when residual gas is discharged from the port space 42.
