Abstract
A pneumatic cryocooler using a pneumatic motor for use in cryogenically cooling superconductors, which pneumatic cryocooler is capable of operation in strong magnetic fields.
Claims7
A pneumatic cryocooler capable of operation in a strong magnetic field, comprising:
- a cryocooler assembly having a first end and a second end,
- the first end comprising a rotary valve, a plurality of ports for a cryogenic fluid, and a motor mount;
- the second end comprising a heat exchanger;
- and
- a pneumatic motor assembly comprising a pneumatic motor, the pneumatic motor assembly operably connected to the motor mount on the first end of the cryocooler assembly;
- wherein the cryocooler assembly is a GM cryocooler assembly, the plurality of ports carrying cryogenic fluid supplies the cryocooler assembly with the cryogenic fluid, and the plurality of ports comprise separate ports for the cyrogenic fluid and a pneumatic fluid, the pneumatic fluid being different from the cryogenic fluid, and the pneumatic fluid being directed to the pneumatic motor.
