Abstract (en)

There is provided a new technology which can operate a plurality of cold heads (14) at the same time asynchronously. A cryocooler 10 includes: a compressor 12; a plurality of cold heads 14 connected in parallel to the compressor 12; a pressure sensor 48 that measures a pressure of a working gas on a supply side from the compressor 12 to the plurality of cold heads 14 or on a collection side from the plurality of cold heads 14 to the compressor 12; and a controller 50 that acquires individual pressure waveform data measured by the pressure sensor 48 when the cold heads 14 are individually operated for each of the plurality of cold heads 14, and operates the plurality of cold heads 14 at the same time asynchronously based on the individual pressure waveform data.
