Abstract:
1. A regenerative cryocooler, the regenerative cryocooler being connected to a compressor configured to make coolant gas have a high pressure, sending the high pressure coolant gas, and absorbing coolant gas having a low pressure, the regenerative cryocooler comprising: a cooling stage extending along and about a central axis and directly connected to a hollow cylinder member having a regenerative material contained therein, the cylinder member being where the coolant gas flows, the coolant gas repeating compression and expansion; two reinforcing members configured to prevent vibration of the cooling stage with respect to a stationary subject to be directly cooled by the cooling stage; and a flange extending along and about the central axis and disposed apart from and facially opposing the cooling stage with the hollow cylinder connected to and between the flange and the cooling stage,
