Abstract

An initial cooling time of a cryocooler (10) is shortened. A method for operating a cryocooler 10 includes: connecting a second compressor 80 in series with a first compressor 12 on a high pressure line 63 or a low pressure line 64; connecting a buffer volume 70 to the low pressure line 64 via a supply valve 72; executing initial cooling for cooling an expander 14 from an initial temperature to a cryogenic temperature in a state where the second compressor 80 and the buffer volume 70 are connected to the cryocooler 10; and executing a steady operation of maintaining the expander 14 at the cryogenic temperature after the initial cooling. The execution of the initial cooling includes supplying a working gas to the expander 14 by using the first compressor 12 and the second compressor 80, and controlling the supply valve 72 to keep a pressure of the high pressure line 63 within a preset appropriate pressure range based on the measured pressure of the high pressure line 63.
